:feature:settings

Purpose: Theme (light/dark/system + dynamic color), language, and sign-out, shown as a dialog rather than a full screen. SettingsViewModel uses SettingsRepository in :data; theme/color/profile values come from JSON DataStore, while language uses app locales.

Gotchas

• The language picker's when maps every non-Arabic locale to English — adding a new values-<lang>/ resource directory changes what generateLocaleConfig offers the system without updating this mapping.

• Sign-out calls Firebase Auth, then resets all preferences, including theme/color settings. It does not delete Room or Firestore records.

• Resubscription can add repository collectors while the ViewModel remains alive; the settings load catch currently constructs a state without storing its error. See subscription lifetimes.

• Follow localization when adding a language; resource files alone do not update the in-app picker/mapping.
