Merge branch 'develop' of https://git.fabrik.mathieu-chavanel.fr/math-pixel/La-Fabrik into develop

While the player is mounted on the e-bike and pressing a movement key,
the persistent 'Descendre du bike' prompt was visible on screen and
polluted the view during gameplay. The InteractableObject is now
unmounted as soon as window.ebikeDriveInputActive flips to true and
remounted the moment the bike comes to a stop.

The driving signal is read in a useFrame and only flips React state
on transitions, so this adds zero per-frame re-renders.

+## Focus Bubble
+
+While the player is in `fragmented`, `scanning`, `repairing` or `reassembling`, `RepairGame` flips `useRepairFocusStore.active = true` and publishes the snapped world center of the repair model.
+
+`RepairFocusBubble` reads the store and:
+
+- renders a `BackSide` sphere (radius 1, scaled 0 → 10m) tinted `#060814` at opacity 0.92
+- grows the sphere with GSAP `expo.out` over 2.5 s when focus turns on
+- shrinks back with `expo.in` over 1.2 s when focus turns off
+- mounts a small "cocoon" decor pass inside (subtle grid floor + soft directional light + ambient) that fades in once the bubble is mostly grown
+
+`Environment.tsx` and `GameStageContent.tsx` consume the same store flag to unmount the vegetation system and the zone debug visuals while the bubble is up, so trees and gizmos do not pierce the shroud. Terrain, water, sky, clouds and grass remain visible behind the bubble.
+
+The bubble is mounted both in `GameStageContent` (production scene) and `TestMap` (physics test scene) so the behaviour matches in both contexts.
