Logout now revokes the refresh token and redirects to the IdP's
end_session_endpoint so the SSO session is fully terminated. The
end_session_url is validated server-side (HTTPS only) before being
returned to the client, preventing open redirect attacks.
Also adds 14 unit tests covering PKCE (including RFC 7636 test vector)
and OAuth discovery (fallback, caching, required field validation).
Add organizer/attendee UI with RSVP buttons (accept/maybe/decline),
contact autocomplete in participant input, scheduling message support
via sendSchedulingMessages flag, and DnD notification for participant
events. Add inline calendar invitation banner in email viewer that
auto-detects .ics attachments, parses event details, and allows RSVP
or import to calendar. Includes cancellation display and 51 tests.
Dark mode color transform had 3 bugs preventing it from working:
- Hook only ran when external content was blocked, not for all emails
- Checked `theme` ('system') instead of `resolvedTheme` ('dark')
- Only transformed CSS style attrs, missing <font color> and bgcolor
Replaced invert+boost algorithm with blend-toward-white for text
(preserves hue, brighter results) and added background darkening
for light email backgrounds. Also handles color/bgcolor HTML attrs.
Fixed long email subjects pushing action buttons off-screen by adding
min-w-0 to the email viewer flex container in the page layout.
Evaluate JMAP CalendarEventAlert triggers client-side and display toast
notifications when alert times are reached. Extracts notification sound
into shared utility and mounts ToastContainer globally (fixes silent
toast failures across all components).
- Pure alert utilities: offset parsing, fire time computation (start/end),
effective alerts resolution with useDefaultAlerts, pending alert filtering
- Zustand persist store for acknowledged alert deduplication (24h retention)
- Global hook with 60s interval check, proactive 24h event fetch via ref
(isolated from calendar store), stale closure protection
- Settings: calendarNotificationsEnabled, calendarNotificationSound toggles
- Toast icon customization, CalendarAlertProvider in layout
- i18n: all 8 locales (EN/FR/JA/ES/IT/DE/NL/PT)
- 44 tests (36 alert utils + 8 notification store), 558 total passing
