Most modals rendered a folds Dialog/Modal with no role and no name, and
their focus traps used `initialFocus: false`, so focus stayed behind the
modal and a screen reader never announced it.
- 32 dialogs with a visible heading: role="dialog", aria-modal,
aria-labelledby → the heading (given an id), tabIndex=-1.
- 4 dialogs that already had a name (Leave Room, room topic viewer,
server ACL, room-nav prompt): role + aria-modal.
- Their focus traps drop `initialFocus: false` for focus-trap's default
(keep an already-focused autoFocus field, else the first tabbable
element) with the dialog itself as fallbackFocus, so a dialog without
a tabbable node can't crash the trap. Traps that live in a parent
(UIA stages, Logout, Forward, Invite) get the semantics only.
- The file drop overlay is deliberately left alone (not a dialog).
Checked at runtime: Join with Address, Delete Message, Report Message,
Leave Room and Logout open as named dialogs with focus inside and close
with Escape (Tab first when a text field has focus — the shared
stopPropagation keeps Escape from discarding typed text, by design).
The axe e2e spec (6 tests) passes; eslint warnings unchanged (46).
17 modals with no heading (image/file viewers, loading screens) remain.

utils/linkSafety.ts compares the registrable domain the visible text claims
(when it looks like a URL/host) with the href's; a mismatch, or a punycode
(IDN) destination, renders the anchor as SuspiciousLink, whose click opens a
confirm — "It shows matrix.lotusguild.org but goes to evil.example." with the
full URL, Cancel / Open anyway (opens in a new tab with noopener). Honest links
are untouched: same registrable domain (youtube.com text over www.youtube.com,
bbc.co.uk over news.bbc.co.uk), plain-word text, mailto:, matrix.to and Lotus
permalinks, anchors with non-text children. Comparator unit-tested (incl. a
Cyrillic-а paypal homograph); verified headless that the phish and IDN
messages are flagged, the honest ones are not, the click shows the confirm and
does not navigate, Cancel keeps you put, Open anyway opens the real target.
