feat(mobile): splash mark, formSheet picker, and catalog guard

[iscekic]

Summary

• On launch, the splash shows dark KILO letters directly on the yellow background, with no box around the letters.
• The language picker opens as a sheet over a dimmed screen. Tap Done to apply the chosen language. Tap Cancel, swipe the sheet down, or use the back gesture to keep the current language.
• The PR review attribution setting, its description, and the remote-command hint in a new chat now appear in every non-English language.

---

The language picker is now a native formSheet route instead of an in-screen Modal. The sheet shows a system grabber and a fading backdrop at a half-height and a full detent, and Done applies while Cancel, a swipe down, or back dismisses without applying. The usePreventRemove guard blocks dismissal while an apply is in flight, and a failed RTL reload shows a Retry sheet instead of the list.

Files

• apps/mobile/src/components/language-picker-sheet.tsx — replaces the Modal with PickerSheet; renders the list, restarting, and reload-failed states at the top level; adds the usePreventRemove guard, a focus reset, and the search remount epoch; moves the search field into a list header.
• apps/mobile/src/app/(app)/_layout.tsx — registers the picker as a formSheet with 0.5 and full detents and a visible grabber.
• apps/mobile/src/app/(auth)/_layout.tsx — replaces the Slot with a Stack, sets login as the initial route, and registers the picker formSheet.

Login and Preferences open the picker by pushing its route and pass per-caller work through a new module-level LanguagePickerBridge. The two picker routes inline their returnTarget literal instead of reading a query parameter, so the query round-trip is gone. The bridge is cleared when a picker route loses focus, so a stale caller callback never fires.

Files

• apps/mobile/src/components/login-screen.tsx — removes the inline Modal state and LanguagePickerSheet render; pushes the auth picker route and sets the bridge with a draft-flush callback.
• apps/mobile/src/components/preferences-screen.tsx — removes the inline Modal state and LanguagePickerSheet render; pushes the app picker route and sets the bridge with a push-token reconciliation callback.
• apps/mobile/src/lib/picker-bridge.ts — adds the LanguagePickerBridge type and its set, get, and clear accessors.
• apps/mobile/src/app/(app)/language-picker.tsx — new route screen; inlines the preferences returnTarget, reads the bridge, clears it on blur, and backs on close.
• apps/mobile/src/app/(auth)/language-picker.tsx — new route screen; same shape with the login returnTarget.

The native splash and the animated overlay now use a transparent letter mark instead of the square logo. The mark is dark letters on transparency at 100 dp over the unchanged yellow background, so a dropped frame cannot show a yellow or black tile, and the dip, punch, disc, and handover choreography is unchanged. The app icon and the login screen keep the square logo.

Files

• apps/mobile/app.config.ts — points the expo-splash-screen plugin at the transparent mark with the unchanged yellow background and width 100.
• apps/mobile/src/components/animated-splash-overlay.tsx — imports the transparent mark instead of the square logo.

Three English-only mobile strings — preferences.prReviewAttribution, preferences.prReviewAttributionSubtitle, and agentChat.newSession.remoteHint — are now translated in all 86 non-English catalogs. The catalog parity check gains an English-identical guard that fails any mobile key whose value equals English in every non-English locale, so an untranslated key can no longer ship silently. The guard carries an allowlist of proper nouns and the two format-only strings that hold no translatable words.

Verification

Two rounds on iOS ran five cases: round 1 ran s1 to s4, and round 2 ran s5.

Case	What it proves	Platform	Result
s1 splash-boot	A cold boot shows the transparent letter mark on the yellow splash and reaches Home.	ios	passed
s2 cold-start-language-picker	A deep link opens the language sheet, and Cancel returns to Home.	ios	passed
s3 login-language-sheet	The globe on the login screen opens the sheet, and Cancel closes it without a language change.	ios	passed
s4 preferences-language-sheet	The language row in Preferences opens the sheet, and Cancel closes it without a language change.	ios	passed
s5 translated-preference	Done applies Spanish in place, and Preferences re-renders with translated strings.	ios	passed

No round reproduced a defect on the unfixed build.

Round 1 recorded the cold boot in /Users/igor/Projects/.scratch/kilo-workflow-mobile-polish-4e1a.SGxkBr/e2e-e2e-r1-ErY3q9/s1-splash.mp4.

Visual Changes

Splash screen. The user now sees a full yellow splash with dark KILO letters and no tile around them on cold boot. In the picture, the dark pixel letters sit at the center of the yellow field with no frame around them.

Language picker sheet, login entry. The globe button now opens a sheet with a search field and a language list over the dimmed login screen. In the picture, the white sheet with one grabber and the Cancel, Language, Done header covers the lower half.

Language picker sheet, Preferences entry. The language row now opens the same sheet over the dimmed Preferences screen. In the picture, the sheet with the search field and the language list covers the lower half above the dimmed toggle cards.

Preferences screen in Spanish. After the user applies Spanish, every Preferences row shows translated copy and the language row shows Español. In the picture, the third card reads Añadir atribución de la app a las revisiones de PR, and the account row reads Idioma, Español.
