sync_settings_widget.dart 68 — the public StatefulWidget and its callbacks
sync_settings_sections.dart 132 — the two sections the screen composes
sync_settings_screen.dart 192 — the State: loading, connecting, build
Uses `part`/`part of`, not imports: _FirebaseSection and _BackupSection are
library-private, so a sibling file cannot import them at all — extracting them
as ordinary files would not compile.
Two shapes tried and rejected on the way: an `extension _BackupActions` on the
State (an extension cannot call the protected setState), and moving build()
out of the class (it is an @override and has to stay). Both reverted from HEAD
rather than patched around.
flutter analyze clean, 29 tests pass.

Extracts the near-identical "Sync settings" UI duplicated across 5 apps
(todo, diet_guard_app, workout_app, wake_alarm/phone_app, home_inventory)
into a single tested package. Firebase sync (primary) + optional local
backup slot; GitHub mirror UI was dropped per kuhy's explicit decision
mid-build in favor of Firebase-only, so existing apps keep their local
GitHub code untouched, just disconnected from this shared screen.
100% line coverage, flutter analyze clean under very_good_analysis.
Generalized check_no_crdt_sync_override.sh to guard any utils git
dependency (crdt_sync, sync_settings_ui), not just crdt_sync by name.
