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.

 - 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`.

    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`).
