Note

Low Risk
Changes are limited to mobile navigation chrome, layout metrics, and internal showcase scripts; routing and deep links stay on the production scheme with no auth or data-path changes.

Overview
Restores the compact T3 Code navigation lockup (wordmark, “Code”, and a build-stage chip) on iPhone and iPad Threads instead of the plain Threads title, while keeping route/linking identity as Threads and accessible heading “T3 Code, Threads”.

Adds CompactBrandTitle and getCompactBrandHeaderOptions, which on iOS liquid glass injects the lockup as a custom leading header item and otherwise uses a custom headerTitle. Stage labels map app variant to Dev, Nightly, or Alpha via resolveMobileStageLabel. Shared HOME_HORIZONTAL_INSET / iPad offsets align the header with compact thread-list content.

HomeRouteScreen clears left header items in split detail mode and reapplies brand options on phone; sidebar shell and main Stack Home screen use the same helper. NativeHeaderToolbarRoot switches to useLayoutEffect so split vs compact layouts do not race on header toolbar registration.

Showcase/screenshot tooling switches from development (t3code-dev, T3CodeDev) to production (t3code, T3Code, APP_VARIANT=production) so captures match store branding (e.g. Alpha chip).

Note

Restore iOS Threads branding in navigation headers using a compact brand lockup component

• Adds CompactBrandTitle component that renders a T3 wordmark, 'Code' label, and a dynamic stage badge ('Alpha', 'Dev', 'Nightly') based on app variant.
• Adds getCompactBrandHeaderOptions() which selects between a transparent title with a native leading item (iOS liquid glass) or a custom headerTitle component for other platforms.
• Updates the Home screen, sidebar, and HomeRouteScreen to use getCompactBrandHeaderOptions() instead of static title strings.
• Fixes split-view layouts in HomeRouteScreen to explicitly clear unstable_headerLeftItems to prevent stale header items.
• Switches useEffect to useLayoutEffect in NativeHeaderToolbarRoot so toolbar items are applied before paint, reducing interim header flicker.
• Updates the showcase build scripts and tests to target the production app variant, package, and scheme instead of development.
