TASK-069: In-app motion

Status: implemented; required checks pass; not yet seen on a device Owner: Claude Reviewer: human product owner

Outcome

The app moves where it used to jump, and what moves is the launcher icon's tea cup.

Cold start: the cup on the icon's blue, steaming, for about a second, then it fades.
Loading: lists show grey placeholder rows with a light passing over them; everything else shows the steaming cup in place of the stock spinner.
The favourite star springs when its state changes.
A screen with nothing to list shows the cup bobbing above its message.
Entering and leaving a screen slides it a short way in from the side it was opened towards.
Pull to refresh brings the cup down with the finger; the steam appears near the release point.
A file's diff arrives row by row the first time it is shown.
Added while this was in progress (product owner, 2026-10-12): switching bottom tabs slides the whole screen sideways, the old tab gliding out as the new one glides in, and the tab's icon springs.

Included: Compose's own animation APIs only. No new dependency.
Excluded: videos made with Claude Motion; any change to what the screens load or show.

Each of the eight items above is in the code and the app builds.
The splash covers the app without delaying it: sign-in, loading and the OAuth callback run underneath, and taps do not pass through the cover.
Moving between code tabs, or between pages of one screen, does not replay the screen transition.
Nothing animates off screen: the pull indicator composes only during a pull, and the diff rows animate once per file, not on scroll.
A list's loading message is still what a screen reader says.
Seen on the product owner's device.

No additional concerns. No network, storage or credential code is touched.
