- The sub-bar was anchored to the MENU button's center + half-height, which
made it spill over the command deck's top rail (buttons are inset below
the bar's top edge). Anchor y is now the deck's top edge so the bar's
bottom edge sits on the deck.
- Update landing.json rocky land-02/03 entries to reference their own
rocky surface/takeoff/shop videos instead of reusing gasgiant/terran
assets, and add the new rocky-shop-03.mp4 video.
- Temporarily disable per-class planet tints in GameScene (option still
accepted by Planet for when we re-enable it).
