- Introduce a `takeoff` video entry in landing.json for each world; missing/
null entries leave the surface instantly (no regression)
- SurfaceScene.takeOff now plays the one-shot take-off clip full-screen,
hides the deck, and only then stops the scene and wakes GameScene
- Guard against a clip that never starts or runs past its duration so the
player is never stranded; finishTakeoff is idempotent
- Update surface-flow/surface-shot dev harnesses to assert and screenshot
the new take-off stage
- Re-map gas giant frames in planets.json from [0,1,2] to [3,4,5] to match
their sheet positions
- New SurfaceScene overlays GameScene when the player requests landing:
plays a one-shot landing clip, then a looping surface clip behind a
dedicated command deck (Shop/Build/Ship + Take Off + Menu).
- Wire comms panel "Request Landing" / "Land" buttons to launch the
surface; TAKE OFF stops SurfaceScene and wakes GameScene so the run
resumes exactly where it left off.
- ActionBar accepts an optional `buttons` override so scenes can supply a
different slot list while sharing layout/colors/animation.
- SavePanel gains a `stateScene` option so saves from the surface read
state from the paused GameScene underneath.
- Add data/landing.json (per-frame video map) and four placeholder
surface clips; CommsPanel now passes its full target payload through to
onAction so landing metadata survives the round-trip.
- Add dev harnesses: headless-Firefox screenshot helper, click-path test
for the real user flow, and a surface-flow assertion suite with parked
screenshot pages.
