Honesty note: an installed PWA that is fully closed cannot reliably fire alarms on Android without a push server (out of scope for v1). Reminders fire while the app is open, and any that came due while it was closed appear as an overdue banner the next time you open the app.
Pick a glass look. "System" follows your light/dark setting.
