From review: sanitizeFilename now denylists only path-hostile + control chars
(preserving Unicode room names instead of collapsing CJK/emoji names to "room"),
converts whitespace to dashes, trims separator runs, and caps length. Also
surface an inline error when canvas.toBlob returns null so a failed PNG encode
isn't a silent no-op.

The invite QR was display-only. Add a "Download QR" button that exports it as a
PNG via an offscreen high-resolution (1024px, spec 4-module quiet zone)
QRCodeCanvas + canvas.toBlob, saved through useSaveFile (filename from the room
name) with the standard download toast. The visible code stays an SVG so it
renders crisply at any size/theme.
Also corrects the stale LOTUS_FEATURES note (the QR is generated locally via
qrcode.react, not api.qrserver.com).

The Share Room QR was fetched from the third-party api.qrserver.com, leaking
which rooms a user shares (and failing offline / under strict CSP). Now rendered
locally via qrcode.react (QRCodeSVG) — no network request, works offline. Added a
white quiet-zone container so the code scans on any theme; dropped the qrError
fallback (local generation can't fail the same way). Removed api.qrserver.com
from the prod CSP img-src (matrix repo). Build verified (rolldown interop OK).
Verification steps added to LOTUS_TESTING.
