/**
 * Dev-only smoke test: boots the game directly into the GameScene
 * (skipping the menu), so the flight scene can be screenshotted/checked
 * without clicking "New Game".
 *
 *   python3 -m http.server 8080
 *   firefox --headless --screenshot shot.png \
 *     --window-size=1280,720 http://localhost:8080/dev/test-game.html
 *
 * Dev hooks (URL params, dev only — ignored by the game itself):
 *   ?ship=<x>,<y>   teleport the ship to a world position after boot
 *                   (screenshots of far-off states — e.g. the off-screen
 *                   compass arrows pointing back at the home world).
 *   ?near=<px>      fly the ship to <px> (edge-to-edge) from the first
 *                   system planet — screenshots the discovery moment
 *                   (rim ping + toast) with the world in view.
 *   ?thrusttest=1   run the Shift+click THROTTLE LOCK flow end-to-end in
 *                   the live scene (synthetic pointerdowns with
 *                   pointer.event.shiftKey set) and paint the verdict
 *                   on the canvas (window.__thrustResult for CDP).
 *   ?tethers=x,y,level;x,y,level  add dev tethers (union-boundary tests)
 *   ?homeLevel=<n>  set the home tether's level (bigger/smaller range)
 *   ?seed=<seed>    use a DETERMINISTIC dev galaxy (same seed ⇒ same
 *                   system, planets, asteroid clusters) — reproducible shots
 *   ?report=1       paint console errors (or "SMOKE OK") on the canvas
