The two Phase 3 "bespoke overlays" aren't content modals: the send-error is an
in-tab glass banner (already consistent — left as-is), and the shutdown screen is
a teardown screen where a blur backdrop would be semantically wrong (should read
as "closing") + risky on the teardown path. Per that finding, apply minor
consistency polish to the shutdown screen only:
- Share the overlay-scrim tone via a new material::OverlayScrimColor(opacity),
used by both the dialog scrim and the shutdown scrim (was a slightly different
hardcoded 0.06/0.06/0.08 → now the 0.04/0.04/0.06 dialog base).
- "Shutting Down" title → theme Warning() amber (was hardcoded gold).
- Force-Quit confirm destructive button → theme Error() (alpha-varied) instead of
hardcoded reds.
No behavior change; the shutdown scrim stays opaque (no blur).
