@inherits LocalizableComponentBase @* One feed item: a post (a boost shows the original and its booster), a notification, or a conversation's last post. The card does its own Mastodon actions (favourite, boost, bookmark, reply, mute, block, delete) and tells the page about replies and deletions. data-post-* attributes tell the globe where the post is (wwwroot/js/globe.js); a quoted post (Compact) has none, since it is not an item of the feed. Located posts have no actions: PrivaPub keeps them off the Mastodon API. Nerd stats are on the time, the author, the place, the media and the counts. *@
