- Skip link: following #main-content left focus on <body> (the <main>
target wasn't focusable), so nothing was announced and the URL got a
stray fragment. <main> is now tabIndex=-1 and the link focuses it.
- Keyboard-shortcuts dialog (?): no role, and focus stayed in the
timeline, so it opened silently. Now role="dialog" aria-modal, and focus
moves into it (Escape still returns focus to where you were).
- Reaction viewer (both the reaction context-menu path and "View
Reactions"): same — role="dialog" aria-modal aria-label="Reactions",
focus moves in.
Keyboard-only checks (Playwright): Tab → skip link → Enter focuses
<main>; Tab reaches the room list, Enter opens a room, typing lands in the
composer, Enter sends (verified on the server); focus ring visible. "?"
opens the dialog with focus inside, Escape returns to the same element,
"?" in the composer stays text. Topic viewer, Search dialog and reaction
viewer all return focus to their opener.

- `?` shortcut now stopImmediatePropagation so RoomView's type-to-focus handler
doesn't steal focus into the composer behind the dialog (and swallow Escape) —
CONFIRMED review finding.
- Typing live region stays mounted (empty when idle) so the FIRST "X is typing"
is reliably announced (a status region added with its text isn't always read).
- Removed a stray empty `{}` JSX expression in MediaGallery (leftover from an
auto-fix).
Reviewer verified the rest: collapsed-message labels, focus-return
classification (4 dialogs fixed, popouts correctly left), and all aria fixes.

- Focus returns to the trigger when closing 4 genuine dialogs (room-topic
viewer, reaction viewer, header topic, Search) — 20 inline popouts/menus
correctly left as-is (returning focus to a hover target would be wrong).
- Typing indicator announced via a visually-hidden role="status" region;
the visual text is aria-hidden to avoid double announcement.
- New keyboard-shortcuts help dialog (press ?, ignored while typing),
mounted in ClientNonUIFeatures.
