thepraandClaude Opus 5.5 6731077191 Dialogs close from a button and rise from the bottom on phones
DModal draws a close button (✕, named by CloseText) beside its heading, in a header that stays in view while the box
scrolls; a long list of who liked a post left only the thin margins around the box to tap out of it. A new
ResponsiveBottom placement makes the box a sheet from the bottom below md and keeps it in the middle from md; the
report, liked-by and boosted-by, edit history and public notice dialogs use it. Boxes are at most 100dvh tall, so a
phone's browser bars don't cut them, and a bottom sheet leaves 3rem above itself and clears the home indicator. The
report dialog gets a Cancel button.

@inherits LocalizableComponentBase
@implements IHandleEvent
@* 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. A CDN-fronted server's post has no point, only
its CDN's group (data-cdn); data-post-at is when it was written, for the globe's Sun; data-uri is its ActivityPub id,
which the e2e tests (tests/e2e) find it by. The persona's filters apply where the page says the card is (FilterIn): a
hide filter leaves it out, a warn filter folds it behind the filter's title, a blur filter blurs its media. Located posts have no actions: PrivaPub keeps them off the Mastodon API. Nerd stats are on
the time, the author and its server's history, the place or the CDN, the media and the counts. *@
