Glyph + spoken label replaces every app-written string on the shared
Sync settings screen and the GitHub device-code dialog (kuhy's
textgate rule). Old sentences are semantics labels; tests find them
there. The device user code stays visible (GitHub's data).

lyricanki's Linux desktop cannot use google_sign_in (no Linux
implementation) and its loopback replacement is dark until a Desktop OAuth
client exists. Hiding the button there makes the screen silently offer less
on one platform, which reads as a bug.
googleUnavailableReason renders a *disabled* button plus the reason. That is
not the "control that can never succeed" trap: the trap is a live-looking
button that reports a fake cancellation, and a null onPressed cannot be
tapped at all. Null stays the default, so every existing host is unchanged.

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.
