A ticked checkbox is filled and raised, and a file input is a thumb-sized neo field

daisyUI fills a ticked checkbox only for a colour variant, so without one it drew a tick on nothing: a checkbox without a
colour now takes the primary colour, filled and raised like a button once ticked (an inset well while not), and a
radio's dot is the primary colour. A file input's own button (Choose File, Browse…) is raised like the app's buttons
instead of daisyUI's flat neutral block, and on a touch screen the file input is 44px tall like the other fields; it had
stayed at its small 32px. Mobile/ControlsTests opens Settings' Data import/export on the narrowest phone, which the
sweep (sections closed) never reached, and photographs it in both themes.

+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## What this is
+
+decePubClient is a Blazor WebAssembly PWA (.NET 10). It is meant as a Pleroma-FE-like client for **PrivaPub**, the
+owner's ActivityPub server, whose repo is `thepra/SocialPub`. It is deployed as a static site at
+https://decepub.thepra.dev, and its API base address is `https://privapub.thepra.dev`
+(`AppConfiguration:ApiBaseAddress` in `wwwroot/appsettings.json`).
+
+It talks to PrivaPub through both of its APIs with one sign-in (see **PrivaPub wiring** below). The feed page has three
+columns: navigation, the feed with a tab per kind of feed, and a 3D globe that follows the posts in view. Nerd stats sit
+in tooltips wherever there is data. Development builds point at a local PrivaPub on `http://127.0.0.1:6970`
+(`wwwroot/appsettings.Development.json`, never published).
+
+`Docs/Insomnia_APIs.json` is an old API collection for a localhost backend. Don't treat it as PrivaPub's API.
+
+## Sibling repo dependency
+
+The project references `../SocialPub/PrivaPub.ClientModels/PrivaPub.ClientModels.csproj`, so SocialPub must be
+checked out next to this repo. CI clones it there. That project supplies:
+- the shared DTOs;
+- `Policies` (IsAdmin, IsUser, IsModerator);
+- the `FieldsNameResource` and `ErrorsResource` localization resources.
+
+Before wiring anything to the API, read `../SocialPub/CLAUDE.md`. PrivaPub's route names (`/peasants/...`, `/mouth`,
+`/anus`, ...) are deliberate. Never "correct" them. The API surface is the Mastodon client API plus PrivaPub's private
+`/clientapi` and `/api/privapub/v1`.
+
+To run against a local PrivaPub: start a mongod, run SocialPub's `PrivaPub` with the Development command in its
+CLAUDE.md on `127.0.0.1:6970` (`Registrations__Mode=Open` lets `/clientapi/user/signup` create a root), then create
+personas with `/clientapi/avatar/private/insert`. Federated posts come from SocialPub's pasture
+(`tools/pasture/run.sh up gts akkoma`, then `tools/pasture/interop.sh gts akkoma`), whose API is `127.0.0.1:6971`.
+Neither DB-IP nor PrivaPub locate private addresses, so for the globe set `RemoteInstance.Geo` in mongo and
+`Statistics:Geo:Self` in PrivaPub's configuration.
+
+## Commands
+
+```sh
+dotnet build decePubClient.csproj                      # what CI runs (-c Release) on every push to master and on PRs
+dotnet run                                             # dev server: https://localhost:7046 / http://localhost:5046
+dotnet publish decePubClient.csproj -c Release -o publish   # static site lands in publish/wwwroot
+```
+
+`global.json` pins SDK 10.0.100 with `rollForward: latestFeature`. There is no linter.
+
+## Testing: end to end against the pasture
+
+`tests/e2e` (Playwright for .NET 1.61.0 on xunit v3) runs the published app in Chromium against SocialPub's pasture: a
+private fediverse of PrivaPub and its peers (GoToSocial, Mastodon, Misskey, Sharkey, Akkoma, Lemmy) seeded with a fake
+community, the town (see `../SocialPub/CLAUDE.md`, "The town"). Never in CI: it needs podman and the pasture.
+
+```sh
+../SocialPub/tools/pasture/run.sh up gts mastodon misskey sharkey akkoma lemmy   # PASTURE_PORT if 6971 is taken
+../SocialPub/tools/pasture/town.sh seed village
+tests/e2e/run.sh [--filter ...]   # publishes with WasmApplicationEnvironmentName=Pasture, serves https://decepub.test, runs
+```
+
+- **The app under test is the deploy's own build** with the environment baked in: Blazor on .NET 10 ignores the
+  `Blazor-Environment` header, so `wwwroot/appsettings.Pasture.json` (API `https://privapub.test`) is chosen at publish
+  time and published only then; the deploy fails if it ever ships.
+- Chromium resolves `*.test` to Caddy on `127.0.0.1:6443` (`--host-resolver-rules`) and ignores the pasture CA. The
+  tests use the Chromium headless shell 1228 cached in `~/.cache/ms-playwright` and never install a browser.
+- **Guards on every test** (`Support/Browser.cs`): the app talks only to its own site and to PrivaPub, a root JWT never
+  goes to `/api` nor a persona token to `/clientapi`, no 5xx, no Blazor error bar.
+- **The tests ask the town** (`Support/Pasture.cs`) which accounts exist and what each object holds (`town.sh expect`),
+  and check the other side of the wire through `town.sh stored`. Each render and action test is also a cell of the
+  town's report (`out/client.jsonl`).
+- Cards carry `data-uri` (their ActivityPub id) and the empty feed `data-feed-empty`, for the tests. The feed renders
+  only the cards near the view, so a test looks for recent cards, and counts what is loaded by `data-feed-count`.
+- **Phones** (`Mobile/`, `Category=Mobile`): `Browser.Open(state, Phone)` opens Playwright's own device presets
+  (shipped in its package): 360×800, iPhone SE (3rd gen), Pixel 7, and the Pixel 7 held sideways, with touch, a coarse
+  pointer and reduced motion; a phone session fails at once if the page doesn't see a touch screen.
+  `SignIn.As(browser, persona, phone)` reuses the desktop sign-in, and any saved sign-in that has expired is renewed.
+  - `RouteSweepTests` measures every page, one screen at a time down its main scroller (`Mobile/fit.js`). It checks:
+    - sideways scroll, unless the strip is marked `data-scroll-x`;
+    - boxes past the screen's sides;
+    - open menus, sheets and dialogs that are cut or outside the screen;
+    - targets without a 44px hit area: hit-tested at their centre and 21px around it, so a crowding neighbour fails
+      them too. Inline links in post text, native media controls and disabled controls are exempt, a fixed floating
+      control covering a target doesn't count, and `data-touch-exempt` exempts one explicitly;
+    - control text under 12px.
+
+    Screenshots, findings and a contact sheet go to `tests/e2e/out/mobile/<run>/`. Cells are `client.mobile.fit.*` and
+    `client.mobile.touch.*`, with the phone as the ref.
+  - `FlowTests` drives the narrowest phone through the menu, a dialog, a new post, a reply, a reaction, a deletion, the
+    full-screen globe, a phone held sideways, a tap into a thread, a picture and the Back button (`client.mobile.flow.*`).
+  - `DesktopUnchangedTests` holds desktop's control sizes.
+- **The globe** (`Render/GlobeTests.cs`): the instruments are built, with the Sun drawn over its subsolar point.
+  - On desktop, a located post written from Milano is pinned, and the globe is photographed in both themes and again
+    turned to the subsolar point.
+  - On a phone, the banner draws little, full screen draws everything with the camera moved back, and closing returns
+    to the banner.
+  - An idle globe draws no frame.
+
+  Photos and stats go to `tests/e2e/out/globe/`.
+- **Restore** (`Category=Restore`, in `Actions/BackupsTests.cs`): a real restore of the pasture from Administration. It
+  ends every session, the town's too, so it runs only when asked (`--filter "Category=Restore"`, never next to other
+  tests) and signs the town in again (`town.sh renew privapub`). Normal runs use `--filter "Category!=Perf&Category!=Restore"`.
+- **Perf** (`Perf/`, `Category=Perf`, left out of the normal runs with `--filter "Category!=Perf"`): `FeedPerfTests`
+  scrolls load0's home (thousands of posts from SocialPub's `load.sh`) to 2000 posts and writes, per step, the time,
+  DOM nodes, JS and .NET heaps and long tasks to `perf.json`.
+- The root project globs `**/*.cs`, so it excludes `tests/**` (`DefaultItemExcludes`), and Tailwind does not scan it.
+
+## CSS: Tailwind 4 + daisyUI 5, vendored, offline
+
+`Styles/app.css` is compiled into `wwwroot/css/app.css` by the Tailwind CSS standalone binary with the daisyUI
+plugin. `app.css` is gitignored and regenerated on every build.
+
+**Nothing in the build or the CI may download from github.com.** Tools live in the repo, and the CSS build runs
+without network access. NuGet restore still uses nuget.org.
+- `tools/tailwind/` holds the pinned tools:
+  - Tailwind 4.3.3 as `tailwindcss-linux-x64.xz`;
+  - daisyUI 5.7.47 (`daisyui.mjs`, `daisyui-theme.mjs`);
+  - daisyUI's component reference, `daisyui-llms.txt`.
+- `.gitattributes` keeps these files byte-exact.
+- `tools/tailwind.sh prepare` checks them against the sha256 values pinned in the script, and unpacks the binary into
+  the gitignored `.tools/tailwind/`. It needs `xz`.
+- Only linux-x64 is vendored.
+- The script's header explains how to upgrade or add a platform.
+- The `TailwindCompile` target in the csproj runs it, so `dotnet build` / `publish` are enough, in CI as well. Debug
+  builds use `--optimize`, Release builds `--minify`. Pass `-p:SkipTailwind=true` to skip it.
+- `IncludeTailwindOutput` adds the generated file to `Content` before static web assets are resolved. Without that, a
+  clean-clone publish would ship `app.css` without its `.gz`/`.br` copies and outside `service-worker-assets.js`.
+  The deploy workflow checks for `css/app.css.gz`.
+- `bash tools/tailwind.sh watch` rebuilds the CSS live next to `dotnet watch`.
+- Tailwind scans every file `.gitignore` doesn't exclude (minus `tools/`, `wwwroot/vendor/`, `Docs/`), and only
+  generates the classes it finds written out **whole**. Never build a class name by concatenation or interpolation (`"btn-" + size`, `$"btn-{size}"`). Write
+  every variant as a literal, e.g. in a switch arm.
+
+Ionicons 4.5 (`wwwroot/vendor/ionicons.min.css`, `<i class="ion-md-...">`) is loaded as its own stylesheet.
+
+## Theme and neumorphism
+
+- `Styles/theme.css` holds two daisyUI themes, `neo-light` (default) and `neo-dark` (`prefersdark`). Every colour
+  is an `hsl()` of `--neo-hue-light` / `--neo-hue-dark` / `--neo-chroma` (0 for the grey themes).
+- `wwwroot/js/theme.js` sets those variables and `data-theme` on `<html>` from `PageSettings`. It runs in `<head>`
+  from localStorage, so there is no flash before Blazor boots. After that, CascadingState calls it through
+  `AppStatusService.ApplyTheme` whenever the settings change. With `PreferSystemTheming` it leaves `data-theme` off,
+  and the OS decides.
+- Change the theme flags through `PageSettings.SetDarkMode` / `SetGray` / `SetHue` and
+  `CascadingState.UpdatePageSettings`, which keep the flags consistent:
+  - choosing light or dark leaves system theming;
+  - picking a hue leaves grey.
+- `AppStatusService.IsDarkTheme()` tells which variant is showing.
+- Settings → General edits every theme setting. NavMenu's toggle and slider are shortcuts to the dark and hue ones.
+  The other sections of Settings belong to the persona (see **Settings** under PrivaPub wiring).
+- `Styles/neo.css` holds the neumorphic layer:
+  - `neo-raised` / `neo-inset` / `neo-flat`, with sizes `neo-2xs` / `neo-xs` / `neo-sm` / `neo-md` (these replace the
+    old `neomorph is-nxsmall` classes);
+  - `neo-gradient(-pressed)` and `neo-hue-track`;
+  - `@utility <daisy-component>` overrides that give btn, input, select, card, … the neo look. daisyUI puts its rules
+    in sublayers of `utilities`, so these overrides beat **every** daisyUI rule. Each override must exclude the
+    daisyUI variants it shouldn't touch, e.g. `:not(:where(.btn-ghost, .btn-link, ...))`, and call sites drop a neo
+    shadow with `shadow-none!`.
+  - Selectors are an inset well; a checked checkbox is filled and raised like a primary button (daisyUI fills one only
+    for a colour variant, and without one drew a tick on nothing), and a checked radio's dot is the primary colour. A
+    file input's own button (Choose File, Browse…) is raised like the app's buttons.
+- Never write `@utility collapse`. It brings back Tailwind's own `collapse` utility (`visibility: collapse`), and
+  every collapse disappears.
+
+## Phones
+
+Below `md` the app is laid out for a phone, and a touch screen gets thumb-sized targets. The rules:
+- **Width and pointer are separate.**
+  - Layout differences between a phone and a desktop use the width variants at the call site (`max-md:`, `md:`).
+  - How big a thing is to a finger uses the pointer: `Styles/touch.css` under `@media (pointer: coarse)`, and
+    `pointer-coarse:` at a call site.
+  - A mouse matches none of it, so desktop keeps daisyUI's sizes (`Mobile/DesktopUnchangedTests` holds them).
+  - A window at most 30rem tall (a phone held sideways) is the `short:` variant.
+- **`touch.css`** is plain CSS in Tailwind's utilities layer, so like `neo.css` it beats daisyUI's sublayers. It sets
+  daisyUI's own size variables:
+  - buttons, tabs, inputs, selects and file inputs are 44px tall;
+  - extra small buttons and the badges that act are 36px, with a transparent `::after` that reaches 44 (5px around
+    the padding box);
+  - checkboxes and radios are 24px, toggles and range thumbs 28;
+  - field text is 16px, so iOS doesn't zoom into a focused field.
+
+  Its `touch-target` utility gives a small link or button a 44px hit area. It can't be used on something that clips
+  its own overflow (a `truncate`d name takes `pointer-coarse:py-3.5` instead), nor on a daisyUI tooltip, which draws
+  its arrow with `::after` (NerdTip takes minimum sizes).
+- **Every target has a 44px hit area on touch,** with 8px between targets in a row (`pointer-coarse:gap-2`). The
+  phone sweep fails anything less.
+- **Overlays on a phone rise from the bottom.**
+  - `DModal Placement="ResponsiveBottom"` is a sheet below md and a centred dialog from md. Every DModal has a visible
+    close button (`ShowClose`, named by `CloseText`).
+  - `DDropdown SheetOnNarrow` turns its content into a bottom sheet.
+  - `Components/PhoneSheet.razor` shows what opens in place on a desktop (the composer, a reply, a quote, an edit) as a
+    sheet on a phone.
+  - All are capped by `dvh`, and the app itself is `h-dvh`.
+- **The Back button closes the newest open overlay** instead of leaving the page.
+  - Overlays register through `IDOverlayHost` (`Components/Daisy`, cascaded from `MainLayout`):
+    - `DModal` and `DDropdown` through the cascade;
+    - the nav menu, `PhoneSheet` and the full-screen globe through `Services/OverlayService.cs`.
+  - `main.js` marks a real Back press (a capture-phase `popstate`), since Blazor can't tell it from the app's own
+    navigation, which closes every overlay and goes on.
+  - No history entries are pushed.
+- **What can't be undone asks first** through `Services/ConfirmService.cs` (`Ask`, shown by `ConfirmHost` in
+  `MainLayout`): deleting a post, taking it off a wall, muting, blocking, leaving a group, dropping a scheduled post and
+  signing out.
+- **On a touch screen:**
+  - a tap on a post opens its thread (`main.js`, `data-thread` on the card, its `data-thread-link`), and cards are
+    pinned to the globe with a mouse only;
+  - a tap on a nerd-stats trigger opens its rows in a sheet (`NerdTip`, `AppStatusService.CanHover`);
+  - pictures open in `Components/MediaViewer.razor`.
+- **The feed on a phone:**
+  - a card's actions are five equal cells (Reply, Boost, Favourite, React, More). Bookmark, the thread and the nerd
+    stats' Details are in More, and the author's picture is in the header;
+  - a new post starts from a floating button;
+  - the globe's banner opens full screen, and a phone held sideways opens it full screen from the tabs;
+  - the feed tabs show their names and fade at the edge where more wait (`edge-fade-x`, `data-scroll-x`).
+
+## daisyUI Blazor components (`Components/Daisy/`)
+
+Every daisyUI component has a `D`-prefixed wrapper (`DButton`, `DModal`, `DDropdown`, `DInput`, ...), grouped by
+daisyUI's categories into folders whose namespaces are imported in `_Imports.razor`. `/styleguide` (not linked) renders
+all of them in every theme. When you add or change one:
+- Map each enum to its classes in a switch with whole literal class names.
+- Value-holding fields derive from `DInputBase<TValue>`, Blazor's `InputBase`, so `@bind-Value` and EditForm
+  validation work. Everything else derives from `DComponentBase` (`Class`, pass-through attributes, `Cx(...)`).
+- Open/active state lives in C# (`@bind-IsOpen`, `@bind-Active`) and is rendered with daisyUI's `*-open` modifier
+  classes. No JS interop.
+  - What daisyUI does with scripts has a script-free equivalent here: `DCheckbox.Indeterminate` renders
+    `aria-checked="mixed"`, and `DCarousel`'s navigation links to the slides' ids, which Blazor scrolls to.
+  - `DCalendar` is the one exception: it wraps the vendored Cally web component (`wwwroot/vendor/cally.js`).
+- Images and links in `/styleguide` stay local (`wwwroot/imgs/styleguide/`).
+- Don't name a parameter after an HTML attribute (`Title`, `Style`, `Id`, `Label`, ...). Blazor matches attributes
+  to parameters without regard to case, so the parameter would swallow the attribute.
+- Components don't use `Localizer` or `CascadingState`; their user-visible strings are parameters.
+
+## Architecture
+
+**Startup (`Program.cs`).**
+- DI registration happens here.
+- The named `HttpClient` "default" uses `ApiBaseAddress` as its base address. It falls back to the host's base
+  address when that setting is empty.
+- `SetDefaultCulture()` (`Extensions/ExtensionMethods.cs`) runs before the app starts. It picks the culture from the
+  saved `PublicCacheData`, or on a first visit from the browser language.
+- Only English (`en-GB`) and Italian (`it-IT`) have resources; any other language gets English.
+- Settings → General changes the language, saves it, and reloads the app.
+
+**`LayerComponents/CascadingState.razor`** wraps the router in `App.razor`. It is the app-wide state object. It handles:
+- `PublicCacheData` (page settings: theme colours, dark/light/system theming, language), persisted in localStorage;
+- the theme, applied through `AppStatusService.ApplyTheme` (`wwwroot/js/theme.js`);
+- `IsOnline` / `IsOffline`, polled every 10 seconds;
+- the session: `IsSignedIn`, `Personas` (the root's), `PersonaId` and `Persona` (its Mastodon `Account`), with
+  `LoadSession`, `SwitchPersona` and `SignOut`. A persona change re-renders every subscriber; pages compare
+  `PersonaId` and reload what belongs to the persona. The JWT is renewed hourly when needed;
+- `ProcessError` / `ProcessWarning`, which log through `ILoggingService` and show a toast;
+- `LogFromJs`, which JS calls back into through a `DotNetObjectReference`.
+
+**Components and pages** inherit `LocalizableComponentBase`, the equivalent of b2b.next's `WidmannComponentBase`. It
+supplies:
+- `CascadingState`, `Localizer`, `Navigation` and `Toast`;
+- `IsLoading`, which starts true, and `IsDefaultDisabled`;
+- `AfterRenderAsyncJobs`, run once after the next render;
+- `WhenOnline` / `StartOnlinePolling`.
+
+`PagesBase` is an empty subclass of it that nothing uses. Never redeclare the base's members in a component.
+
+**UI feedback.**
+- `Services/ToastService.cs` is the snackbar: the SUtility extensions `AddResponseError(WebResult)` (silent on
+  410/cancelled; connectivity failures show as warnings), `AddResponseError(string)`, `AddResponseSuccess` (closes
+  after 5 s), `AddWarning` and `AddException`. `Components/ToastHost.razor`, placed in `MainLayout`, shows the
+  messages.
+- `Components/ErrorViewer.razor` shows in-page errors: the cascading `EditContext`'s validation messages,
+  `AdditionalError` and `AdditionalErrors`.
+- `ConfirmService` asks before what can't be undone (see **Phones**).
+
+**HTTP (`Services/IHttpService.cs`).**
+- Routes are constants in `Models/APIs.cs` (b2b.next naming: `GET_`/`POST_`/`DELETE_`, `_M_` for routes built from
+  parameters), relative to `ApiBaseAddress`.
+- The route picks the credentials: `clientapi/` sends the root's JWT, `api/` the current persona's Mastodon token
+  (exchanged when missing, exchanged once more and retried when PrivaPub refuses it), `oauth/` nothing.
+- It also picks the JSON: `SUtility.MastodonSerializer` (snake_case, `MastodonJsonContext`) for `api/` and `oauth/`,
+  `SUtility.DefaultSerializer` (camelCase, enums by name like PrivaPub, `ClientJsonContext`) for `clientapi/`. A payload
+  can be an object (JSON), name/value pairs (a form) or a `Func<HttpContent>` (multipart), built once per attempt.
+- Auth levels: `Get` / `Post` / `Put` / `Patch` / `Delete` need credentials and end the session when PrivaPub refuses
+  them; `GetAnon` / `PostAnon` add them when there are some; `*TotallyAnon` send none (the login must not carry a JWT:
+  PrivaPub redirects it).
+- `retryOnError` backoff: 1, 2, 4, 8, 16, 29 s, then 60 s, for at most 10 minutes.
+- Each request has its own timeout (`Measure`): 100 s, or 10 minutes for a multipart body (an upload); the
+  `HttpClient`'s own is off.
+- Failures never throw. They come back as responses carrying an invalid `WebResult`, with an `ErrorCode` from
+  `Models/FailureCodes.cs`; a cancelled request comes back as HTTP 410.
+- Read failures with `ReadWebResult` (it understands `WebResult`, validation ProblemDetails and Mastodon's
+  `{"error": ...}`) and bodies with `DefaultReadFromJsonAsync` / `MastodonReadFromJsonAsync`; a body that doesn't fit
+  comes back as the default and is written to the browser console. `PageCursors()` reads `max_id`/`min_id` from `Link`.
+- Every request PrivaPub answers is recorded in `RequestStats` (method, route template, status, duration, size, rate
+  limit headers; never a body or a token), for the nerd stats.
+- PrivaPub's `WebResult` gets `IsInvalid` from `Extensions/WebResultExtensions.cs`, a C# 14 extension property.
+
+**PrivaPub wiring.**
+- **One sign-in** (`Services/AuthService.cs`, `Pages/Login.razor`): the root signs in on `/clientapi/user/login`, then
+  each persona the client uses gets its own Mastodon token in exchange for the JWT (PrivaPub's `PersonaExchange`,
+  RFC 8693 on `/oauth/token`, first-party client id `AppConfiguration:ClientId`). `AuthData` keeps the JWT and the
+  persona tokens; logout revokes every persona token, then forgets the session and IndexedDB.
+- **Services** (`Services/`): `TimelineService` (every feed as `FeedPage`s of `FeedPost`s, paged by `max_id`/`min_id`;
+  circles are read as ids from `/clientapi` and hydrated through `/api/v1/statuses?id[]=`; located posts come from
+  `/clientapi/post/nearby` and have no Mastodon actions), `StatusService` (publish, favourite, boost, bookmark, delete,
+  threads, mute, block, poll votes, emoji reactions through Pleroma's `/api/v1/pleroma/statuses/:id/reactions`, joining and
+  leaving remote events through `/api/privapub/v1/statuses/:id/join|leave`; located and group posts go through
+  `/clientapi/post/insert`, and a located post's author deletes it through `/clientapi/post/delete`, its card's one action), `AccountService` (profiles, relationships, follow,
+  block, mute, follow requests, `/api/v2/search`, whose handles and URLs PrivaPub resolves), `ListService` (the
+  persona's lists and their members; members are only accounts it follows, found with `accounts/search?following=true`),
+  `FilterService` (the persona's v2 filters, their keywords and filtered posts), `DiscoveryService` (hashtags and
+  following them, trends, the directory), `PortabilityService` (Mastodon's CSV exports and imports), `AdminService`
+  (`/clientapi/moderator` and `/clientapi/admin`), `MediaService` (uploads), `GroupService`, `InstanceService` and
+  `ProvenanceService`.
+- **Reactions and votes are public** (owner decision, PrivaPub's ROADMAP): before a persona's first reaction or poll
+  vote, `PublicNoticeService` asks it once (`PublicNoticeHost` in `MainLayout`) and remembers the persona in
+  localStorage (`PublicActionNotices`). Anything else that makes a persona's act visible to others gets the same notice,
+  with its own `PublicAct`: joining an event (owner decision 2026-10-05) is asked once more, since the event's server
+  shows who takes part. An event card shows the persona's participation (`privapub.event.participation`: pending,
+  accepted, rejected) with Join or Leave, except for events by invitation or taken on another site (`join_mode`).
+- **What a card shows of other platforms:** custom emoji (`Helpers/CustomEmojis.cs`: a post's or account's `:shortcode:`
+  in its text, name, warning, bio and fields, as the picture the server listed, never inside a tag), a threadiverse
+  post's downvotes next to its favourites, blurhash placeholders until a picture loads (`wwwroot/js/blurhash.js`
+  paints any `[data-blurhash]`: a picture's until it loads, again when its source changes, and for good behind the
+  sensitive-media button), a picture's focal point (`object-position`), and an event's online link, participants and
+  status. A picture, video or sound that fails to load says "Media unavailable" with "Open original"
+  (`data-media-unavailable`), and a gifv plays only on a tap under `prefers-reduced-motion`.
+- **Profiles and search** (`Pages/Profile.razor` at `/account/{id}`, `Pages/Search.razor` at `/search?q=`): a card's
+  author and a notification's account open the profile in the app; "Open original" is the only way to the remote site.
+  A profile shows the posts the account pins above its posts (`pinned=true`: what an account elsewhere features); the
+  persona pins and unpins its own public and unlisted posts from the card's menu.
+  An account that moved says where to (`Account.Moved`, which PrivaPub fills once the new account names the old one),
+  linking the new account's profile.
+  Another's profile and posts can be reported (`Components/ReportDialog.razor`, `/api/v1/reports`): a category, words,
+  and for a remote account a copy to its server, which PrivaPub sends from its own actor, never naming the persona.
+  Who liked or boosted a post opens from its card's menu (`Components/InteractedByDialog.razor`).
+- **Walls** (Smithereen's, FEP-400e): a post written on someone's wall says whose (`privapub.wall`, `data-wall`, linking
+  that profile); one written on the persona's own wall is taken off from the card's menu (`DELETE` on the status, which
+  PrivaPub turns into a `Remove` that Smithereen takes for a deletion). Only the persona's followers may write there.
+  A card in a fixed-height flex column with `overflow-hidden` needs `flex-none`, or it collapses to nothing.
+- **Groups** (`Pages/Groups.razor` at `/groups`): the persona's communities and circles (`GroupService`, `/clientapi/group`):
+  made (a circle unless it is a community, with an invitation code and an optional password), joined by invitation and
+  left; the ones it runs edited, their invitation shown, the requests to join let in or declined, members taken out.
+  Only a group's owner and moderators see who is in it.
+- **Lists** (`Pages/Lists.razor` at `/lists`): made, renamed, given a replies policy and made exclusive (their members
+  leave the home feed) there, filled from the accounts the persona follows; a followed account's profile has a Lists
+  menu too. A list is read as the feed's Lists tab (`FeedFilter.ListId`). Lists never leave PrivaPub.
+- **Filters** (`Pages/Filters.razor` at `/filters`, linked from Settings): PrivaPub marks every status with the filters it
+  matches (`Status.Filtered`), whatever their context; a page tells each card where it is (`Content.FilterIn`: home and
+  lists, notifications, public feeds, threads around the opened post, profiles; none for favourites, bookmarks,
+  conversations and search), and the card leaves the post out (hide), folds it behind the filter's title (warn) or blurs
+  its media (blur).
+- **Articles** fold in a feed (`Content.IsFoldedArticle`): an Article or a Page with its title, or a titled post longer
+  than a few paragraphs (WriteFreely sends Notes with a name), shows its cover, its excerpt and a Read button; the
+  post opened in its thread shows whole.
+- **The composer** (`Components/Composer.razor`) writes a post, a reply (`InReplyTo`), a quote (`Quoting`, offered on a
+  card when the server says the persona may quote it) or an edit of the persona's own post (`Editing`); a post can hold
+  a poll instead of media.
+  - **Media are uploaded as soon as they are picked** (`Services/MediaService.cs`, `Models/UploadMedia.cs`):
+    - each is streamed from the browser's file, and only a 320 px thumbnail (`RequestImageFileAsync`) is kept to show it;
+    - each shows its state (`data-upload-state`: uploading, processing, ready, or failed with Retry);
+    - audio and video PrivaPub answers 202 for are followed (`GET /api/v1/media/:id`, 206 until ready);
+    - the ids are kept, so a post that fails never uploads its media again;
+    - the types and sizes accepted are PrivaPub's own (`/api/v2/instance`, `MediaService.Limits`);
+    - a description changed after the upload is PUT before the post.
+  - **Alt text:** publishing a picture without a description asks once (`data-alt-reminder`, "Publish anyway"), unless
+    the reader turned `PageSettings.RemindAltText` off in Settings → General.
+  - **Edits send the whole post, as Mastodon wants it:** its words and warning from `/source`, its own language and
+    sensitive flag, the media it keeps or adds (`media_ids`; removing them all is `[]`), and the descriptions changed
+    (`media_attributes`). Its visibility and poll stay.
+  - A new post's media are sensitive when the persona's "always mark media as sensitive" (`source.sensitive`) says so.
+  A mention or hashtag being written at the end of the words is offered what PrivaPub already knows
+  (`/api/v2/search`, never resolving), once typing pauses.
+  An edited post's card says so, and its versions open from there (`/statuses/:id/history`, newest first; PrivaPub
+  keeps a remote post's earlier versions from its edits and from Pleroma's `formerRepresentations`).
+- **Threads** (`Pages/ExpandMessage.razor` at `/expand/{id}`): opening a remote thread makes PrivaPub read its replies
+  from their servers (its FEP-7888 `context`, else `replies`), so the page reads the thread again after 4 and 15 seconds
+  and adds what was found, in the thread's order.
+- **Interaction policies** (GoToSocial's, and FEP-5624's `canReply` on a PeerTube video whose comments are moderated): a
+  reply or boost whose target's author must approve it shows so on its card (`privapub.approval`: pending, then nothing
+  once approved, or rejected); one the policy shuts out is refused by PrivaPub (422) and shown as an error.
+- **Settings** (`Pages/Settings.razor`, `Components/Settings/`): the login itself (`AccountEditor`: its password changed,
+  or the whole of it deleted, every persona with it, through `/clientapi/user/update/password` and `/clientapi/user/delete`;
+  the client then signs out), the persona's profile (`ProfileEditor`:
+  `update_credentials` as multipart, its words as written from `Account.Source`, pictures (streamed from the file,
+  and removed with `DELETE /api/v1/profile/avatar|header`), fields, locked, bot,
+  discoverable, indexable and posting defaults; the composer starts a new post at its default visibility), its mutes,
+  blocks and blocked servers (`MutesAndBlocks`), and `DataTransfer`: follows, lists, blocks, mutes, blocked servers
+  and bookmarks exported and imported as the CSV files Mastodon writes, so a persona moves between servers. An import
+  resolves each row through PrivaPub and acts one row at a time; it can be stopped. Above it, `PersonaArchivePanel`
+  (`ArchiveService`, `/clientapi/persona/{id}/archive`; owner decision 2026-10-07): the persona's whole archive made on
+  PrivaPub in Mastodon's layout and downloaded through a link; and an archive (its own, or Mastodon's) uploaded in pieces
+  by `js/transfer.js` and imported into it, the parts chosen (likes, located and scheduled posts off unless ticked),
+  with progress, a report and Stop. Imported posts are delivered to no one.
+- **Administration** (`Pages/Administration.razor`, `Components/Admin/`, for moderators): reports, then for
+  administrators the servers blocked for everyone, the federation statistics and the backups. PrivaPub has no admin list
+  of users, and adding an admin endpoint waits for the owner, so the Users section stays empty.
+- **Backups** (`Components/Admin/BackupsPanel.razor`, `/clientapi/admin/backups`; owner decision 2026-10-07): the server's
+  backups (nightly, before each deploy, made here, uploaded), with what runs and the last restore's report.
+  - A download asks for the password and gives a link good for ten minutes, a plain anchor, so the browser saves the tar
+    to disk.
+  - An upload never passes through .NET's memory: `wwwroot/js/transfer.js` PUTs `file.slice` pieces at the offset PrivaPub
+    has, and carries on from what PrivaPub says after a refused or lost piece.
+  - A restore asks for the password and the server's host typed out, and says what it means. PrivaPub stops, restores as
+    it starts again and ends every session, so the page shows it restarting until the ended session sends it to sign in.
+- **Notification policy** (`Components/Settings/NotificationPolicyEditor.razor`, in Settings and at `/notifications/filtered`):
+  what notifications from people the persona does not follow, people who do not follow it, new accounts, private
+  mentions it did not ask for and limited accounts become (accept, filter, drop; `/api/v2/notifications/policy`), and the
+  filtered ones, one request per account, let in (with that account from then on) or dismissed. The Notifications tab
+  links there while requests wait.
+- **Scheduled posts** (`Pages/Scheduled.razor` at `/scheduled`): the composer's clock button gives a Mastodon API post a
+  time (`scheduled_at`, at least five minutes ahead; located and group posts have none); the page moves or drops them.
+- **Explore** (`Pages/Explore.razor` at `/explore`): trending hashtags, posts and links (PrivaPub's, from public posts
+  it holds), the directory, and the hashtags the persona follows. A hashtag's feed tab follows it too.
+- **Mastodon DTOs** are client-side, in `Models/Mastodon/` (snake_case). `/clientapi` DTOs come from
+  `PrivaPub.ClientModels`.
+- **Where a post is** (`InstanceService.Locate`, `Models/FeedPost.cs`): its own place (Pixelfed's, `privapub.place`),
+  its event's venue, the reader for a located post, its author's server (to 0.1°, or a point in its country from
+  `Helpers/CountryPoints.cs` when DB-IP located it only to a country), or, for a CDN-fronted server, its CDN's group
+  (`LocationSource.Cdn`: no point, a `CdnKey` and the place `Before` the CDN). Server descriptions are cached a day in
+  localStorage (`ServerInfos`); a server's weekly history (`/instances/:host/history`) and a CDN's page (`/cdns/:key`)
+  are read on the first hover and kept for the session. PrivaPub's own host is the signed-in persona's account host,
+  since the API may be reached under another name.
+- **The feed page** (`Pages/Index.razor`): `FeedTabs`, `Content` (the card, which does its own actions), `Composer`,
+  `GlobePanel`. Leaving it keeps the feed in `Services/FeedMemory.cs` (its posts, waiting posts, cursors and scroll,
+  ten minutes, for the same feed of the same persona), so coming back from a thread or a profile shows it again at once
+  without reading it anew. Older pages load as the end comes near (`wwwroot/js/feed.js`). Newer ones come through PrivaPub's
+  streaming API (`Services/StreamingService.cs`: one WebSocket, the persona's token as its protocol, never in a URL)
+  for home, lists, local, federated, hashtags and notifications, and wait behind a "new" button; a deletion or an edit
+  it tells applies at once. Other feeds, and any feed while the stream is down, are polled every 45 s while visible.
+  - **At volume:** the list is a `<Virtualize>` (only the cards near the view are rendered), and a card re-renders only
+    when its own events run or its render key changes (`Content.RenderKey`: the post, its status, notification,
+    conversation, place, grouping, where it is shown, the persona and the connection). Anything that changes what a
+    card shows from outside it must replace one of those objects or be added to the key; mutating one in place leaves the
+    card as it was. Without these a feed took seven minutes to reach a thousand cards and held 900 MB at two thousand.
+- **The globe** (`wwwroot/js/globe.js`, an ES module imported by `GlobePanel`) runs on globe.gl, vendored in
+  `wwwroot/vendor/globe/` with its textures and `countries.json` (`SOURCES.md` has versions, licences and hashes; the
+  service worker never precaches it). It looks at the spherical mean of the located posts in view, pulses and draws an
+  arc to a hovered post, honours `prefers-reduced-motion`, and draws only while something moves (idle, it costs no GPU
+  time; `wake()` before anything that animates).
+  - **Map.** Each pixel computes its own map coordinates from its point on the sphere (`sharpen`), so the poles don't
+    pinch; the maps wrap horizontally and get 8× anisotropic filtering (`keepSharp`). The day texture is NASA's, its
+    seam repaired by `tools/globe/prepare-day-texture.py` (dev-only, needs Pillow).
+  - **Sun.** `wwwroot/js/sun.js` (pure functions of a date: the subsolar point, Earth–Sun distance, seasons, a place's
+    elevation, phase of the day, solar time and day length) lights the globe in the shader: the day map shaded by the
+    Sun's height and distance, city lights on the night side, a twilight blend between. It shows now (refreshed every
+    30 s), or the moment of the hovered, focused or pinned post (`data-post-at` on the card; a click pins a card,
+    `data-globe-pinned`), and tells `GlobePanel` through `SunChanged`, which shows the moment and its phase at the panel's
+    top and keeps the Sun's numbers as screen-reader text (`aria-describedby`). The theme changes only the atmosphere and
+    the points.
+  - **Instruments** (`wwwroot/js/instruments.js`; owner decision 2026-10-06: the nerd stats drawn where they belong, not
+    a table). The globe has no tooltip. What it draws:
+    - the Sun: its ray and bead over the subsolar point, the day/night line and the twilights, the declination, the
+      noon and midnight meridian, and its analemma at this hour to the next equinox or solstice;
+    - a focused post's place: its horizon, its Sun's height and its day lit on its latitude;
+    - the tropics, the polar circles and the CDN ring;
+    - the view's centre and spread, and rings around the posts in view;
+    - a small orrery in the top left corner, re-anchored to the camera before each render.
+
+    The numbers are chips in a DOM overlay (`.globe-instruments`, `aria-hidden`), placed after each frame globe.gl renders
+    (`scene.onAfterRender`), clear of each other, the moment's caption, the orrery and the legend. The frame rate is a
+    ring around the globe; what is left is a legend in the bottom left. Geometry changes only inside a wake globe.js
+    already made, so an idle globe still draws nothing.
+    - three.js's classes come from objects globe.gl made (`classesOf`), never `window.THREE`, since that would mix two
+      copies. three.js sets its `is*` flags on instances, so the lookup checks instances. globe.gl adds its globe on its
+      first update, after `new Globe()`, so the parts are built before the first render that finds it. Without the
+      classes, only the ring and the legend remain.
+    - A canvas under 320px tall (a phone's banner) gets the day/night line and the subsolar point only; full screen
+      gets everything.
+  - **Countries.** Land borders as thin paths, and names placed by `placeLabels`: largest countries first, once they
+    span enough pixels, away from the globe's edge and clear of each other, in the reader's language
+    (`Intl.DisplayNames`). `countries.json` is built by `tools/globe/prepare-countries.py` from world-atlas (Natural
+    Earth). The label renderer owns `display`, so labels hide through `visibility`.
+  - CDN-fronted posts are labels per CDN on a ring at 68°N, never a place; hovering one draws its arc there and a ring
+    where the server was before the CDN. The posts' places reach it in one call per feed change; cards are matched by
+    `data-post-id`.
+- **Nerd stats** (`Components/Nerd/NerdTip.razor`, rows from `NerdRow`): a post's ids, times and provenance (read on
+  hover), its author and server with the server's changes of place and CDN week by week, its place or its CDN (how
+  PrivaPub found it, the place before it, the CDN's servers week by week), media and counts; the feed's paging and last
+  request. The globe's are its instruments (see **The globe**), with no tooltip and no poll.
+
+**Localization (`Services/CoalescingStringLocalizer.cs`).**
+- Lookup order: this repo's `Resources/AllStrings.resx` (+ `.it.resx`), then `FieldsNameResource`, then
+  `ErrorsResource`.
+- A missing key renders as the key itself, formatted with its arguments, so a typo fails silently.
+- The class lives in namespace `collAnon.Client.Services`, a leftover from another project.
+- `Resources/ErrorMessages.resx` is read by `[Required]` / `[StringLength]` through `ErrorMessageResourceType`. A new key
+  needs its `public static string` property in `ErrorMessages.Designer.cs` too, or validation throws at runtime.
+
+**Client storage** comes in two layers:
+- **localStorage** (Blazored.LocalStorage, camelCase JSON) holds `AuthData`, `PublicCacheData`, `FeedFilter` and the
+  server cache `ServerInfos`, keyed by `nameof(Type)`.
+- **IndexedDB** (DnetIndexedDb, database `data`) is reached through `IStorage`. Its schema is declared in
+  `GenericExtensions.AddIndexedDb()`, and you must bump `WithVersion` when you change it.
+- The schema is at version 3: the `ClientLogs` store that `IStorage.AddLog` writes (version 2 added it; version 3 left
+  the mock feed's `Message` store out).
+
+**Auth.** `TokenAuthStateProvider` holds `AuthData` (localStorage, cached in memory) and builds the auth state from
+it: the root's name, its policies as claims, and the current persona. Pages that need a session carry
+`[Authorize]`; `RedirectToLogin` sends the reader to `/login?returnUrl=…`.
+
+**JS interop.**
+- `wwwroot/main.js` defines `window.*` helpers. `Services/AppStatusService.cs` calls them, mostly through the
+  synchronous `IJSInProcessRuntime`.
+- Each helper reports its errors back through `window.logFromJs`.
+- The other scripts (IndexedDB, HeadElement, rxjs) are loaded by `<script>` tags in `wwwroot/index.html`; the feed's
+  modules (`js/feed.js`, `js/globe.js`) are imported on demand through `IJSObjectReference`.
+
+**PWA.** Published builds use `wwwroot/service-worker.published.js`, and `service-worker.js` is the dev version.
+
+## Development rules
+
+These rules are adapted from the owner's b2b.next project. They are enforced by review: the build doesn't check them,
+so follow them in every change.
+
+| Area | Rule |
+|---|---|
+| All | `var` everywhere; uninitialised locals are `var x = default(T);` |
+| All | Primary constructors for DI (`class Foo(IBar bar)`), not constructor + fields |
+| All | Every async method takes a `CancellationToken` as its last parameter |
+| All | Early return on error: guard, handle, `return`; never if/else for success vs failure |
+| Models / state | Lists and arrays `= []`, never null; no `= string.Empty` / `""` defaults; explicit enum defaults |
+| Components | No `@{ }` blocks in markup: locals become `@code` members |
+| Components | `[Inject]` in `@code`, never `@inject` |
+| Components | Disable controls with `IsDefaultDisabled` (plus local conditions), never bare offline state |
+| Components | Every text/number input declares `autocomplete` |
+| Services | `Task<WebResult>` for mutations, `Task<List<T>>` (`[]` on error) for lists, `Task<T>` with a default for values |
+| Localization | Every user-facing string through `Localizer`, its key in **both** `AllStrings.resx` and `AllStrings.it.resx` |
+
+**CancellationToken.** It goes on every async method in services, `CascadingState` and helpers, defaulting to
+`default`; pass it on to what you call. Exempt: Blazor lifecycle overrides, `[JSInvokable]` methods, framework overrides
+(`GetAuthenticationStateAsync`), and private UI handlers bound from markup.
+
+**State initialisation.** Initialise page and component state (`= new()`, `= []`) and bind it directly. No passthrough
+getters and no `?.` chains over state that can't be null:
+
+```csharp
+List<FeedPost> posts = [];                      // DO
+@posts.Count                                    // DO
+@(posts?.Count ?? 0)                             // DON'T
+```
+
+`= ""` is allowed only as a documented exception, with the reason in a comment (e.g. a decorative image's `Alt`).
+
+**Pages that load data.** Pages fetch in `LoadData` and keep lifecycle concerns in the lifecycle method:
+
+```csharp
+protected override async Task OnInitializedAsync()
+{
+	if (CascadingState.IsOffline)
+	{
+		WhenOnline(LoadData);
+		StartOnlinePolling();
+		IsLoading = false;
+		return;
+	}
+
+	await LoadData();
+	IsLoading = false;
+}
+```
+
+- Reuse the base `IsLoading`; don't add per-section loading flags.
+- A component that binds `IsDefaultDisabled` must set `IsLoading = false` once it is ready, even if it loads nothing;
+  otherwise its controls stay disabled.
+- Never wrap a service call in try/catch. Services already catch and log, and return an invalid `WebResult`. Branch on
+  `result.IsInvalid` instead:
+
+```csharp
+var result = await StatusService.Delete(Status.Id);
+if (result.IsInvalid)
+{
+	Toast.AddResponseError(result);
+	return;
+}
+
+Toast.AddResponseSuccess(Localizer["Message deleted."]);
+await OnDeleted.InvokeAsync(Post);
+```
+
+**Client services** follow b2b.next's two patterns (see its `StoreService`):
+- Create `var result = new WebResult();`, call `httpService` inside a try/catch, and on a non-success status
+  `result = await response.Content.ReadWebResult(response.StatusCode, localizer, ct)`. Log with `ILoggingService`.
+- Return `result` (mutations) or `[]` (lists), and set `result.Data` on success.
+- POST bodies are JSON payloads for `/clientapi` and the Mastodon API (snake_case DTOs), forms for `/oauth`.
+
+**In-page errors.** `ErrorViewer` takes `AdditionalError` for one message and `AdditionalErrors` for a list. Never
+join a list into one string with `<br/>` or `\n`.
+
+**Autocomplete values:**
+- `autocomplete="off"` for search, filter and free text;
+- `new-password` when setting a password;
+- `one-time-code` for OTP (DOtp sets it);
+- `username` and `current-password` on the login form, so password managers fill it;
+- inside `Components/Daisy`, attributes pass through from the caller.
+
+**Localization:**
+- Keys are English source strings. Grep both resx files for an existing key before adding one; match keys exactly.
+- Never add a key that differs from an existing one only by case ("users" next to "Users"): resource lookups collide
+  on them and one of the two silently shows the other's text. Reuse the existing key.
+- Use `Localizer[key, args]`, never `string.Format(Localizer[key], …)`. Don't write `.Value`.
+- Enum members shown through `Localizer[value.ToString()]` are keys too: when you add a member, add its key.
+- Language names in the language picker stay in their own language.
+
+**Formatting.** Date formats come from `SUtility.dateTimeFormat` / `timeFormat` / `dateTimeFormatExt`. Relative times
+and sizes come from `GetPassedTime` / `GetFileSize` (`Extensions/GenericExtensions.cs`). No inline format strings for
+display.
+
+**JSON.** Register every `/clientapi` or localStorage type in `ClientJsonContext.cs` (camelCase: `theme.js` reads
+`pageSettings` straight from localStorage), every Mastodon API type in `MastodonJsonContext.cs` (snake_case).
+
+**Wiring a feature to PrivaPub:**
+1. For `/clientapi`, add the request/response DTOs to `PrivaPub.ClientModels` in the SocialPub repo: `View*` for
+   responses, `*Request` for requests, `*Form` for forms with validation. Lists `= []`, no string defaults. For the
+   Mastodon API, add the shape to `Models/Mastodon/`.
+2. Register them in `ClientJsonContext` or `MastodonJsonContext`, and the route in `Models/APIs.cs`.
+3. Add a client service method that calls `IHttpService` against the server's route, following the patterns above.
+4. Wire the page with early returns, toasts and/or an `ErrorViewer`.
+
+**Not adopted from b2b.next, on purpose:**
+- **The `tw:` Tailwind prefix.** b2b.next needs it next to MudBlazor's CSS; here daisyUI is the only component CSS.
+- **Server-only rules:** no 5XX responses, the controller pattern, `IOptionsMonitor`, data access and caching.
+- **b2b.next-specific features:** Excel import/export, password policy, legacy porting rules, the `{culture}` route
+  placeholder (PrivaPub's routes are absolute `/clientapi/...`), and the release/API-status worker.
+- **Mandatory `/// <summary>` on every `[Parameter]`.** Document only what isn't obvious from the name.
+
+## Deployment
+
+Both workflows check the repo out with a plain `git fetch` from this Gitea, not `actions/checkout`, because the runner
+would download that action from github.com. Never add a `uses:` step.
+
+`.gitea/workflows/deploy.yml` runs on a `v*` tag or a manual dispatch, on a self-hosted runner that is also the web
+host. The steps:
+1. Publish the site.
+2. Write `build.json` (commit, ref, time).
+3. Snapshot the live directory to `/var/backups/decepub.thepra.dev`.
+4. `rsync --delete` into `/var/www/decepub.thepra.dev`.
+5. Check that `build.json` serves the new commit and that a deep client route returns 200 (the SPA fallback). Otherwise,
+   roll back to the snapshot.
+
+The nginx vhost and headers are in `deploy/nginx/` (it sends `X-Robots-Tag: noindex, nofollow`), and
+`deploy/max/setup.sh` is the one-time root setup on the server. If you add a file that must never be cached, add it to the `expires -1` locations in the vhost.
+
+## Conventions
+
+- Indent with tabs.
+- `Nullable` is disabled and `ImplicitUsings` is enabled.
+- Global Razor usings are in `_Imports.razor`.
+- Styling uses the D components, Tailwind utilities and the `neo-*` utilities. Use `gap-*` rather than `space-x/y-*`
+  on flex containers; the feeds use `flex-col-reverse`, which `space-*` gets wrong.
+- `SUtility.IfTrueThen(cond, "class")` is the helper for conditional classes.
