- GameScene now passes the world's type label and tether level into the SurfaceScene launch payload; new tetherLevelFor() resolves a world's anchored tether (by label or anchor position) for that line.
- SurfaceScene builds/decodes a two-line HUD (Ethnocentric name in the menu title shade with black stroke, Centauri line below) while the surface clip loops, driven by the shared scramble decode; it is torn down on take-off and shutdown.
- landing.json gains a hud config block for margins, fonts, spacing, strokes, and colors.
- Added dev-only harnesses (surface-hud.html/.mjs test page and surface-hud-shot.html/.mjs screenshot probe) to verify the HUD styling, decode settle, payload, and teardown in headless Firefox.
