/**
 * Dev-only SURFACE HUD test: boots into the GameScene, lands on the home
 * world, and checks the new upper-left HUD (SurfaceScene.buildHud):
 *
 *   - the launch payload carries the world's type + tether level
 *   - the name text: Ethnocentric (header face), the menu title's shade
 *     (data/menu.json → colors.title), a black stroke behind it
 *   - the line below: "TYPE, TETHER LEVEL N" in the body face (Centauri)
 *   - both lines decode in (the shared scramble) and settle on the
 *     final strings
 *   - destroyHud() tears it down (take-off/shutdown path)
 *
 *   python3 -m http.server 8124
 *   node dev/cdp-firefox.mjs http://127.0.0.1:8124/dev/surface-hud.html \
 *     'return window.__SURFACE_HUD_TEST__;'
