- src/ui/Menu.ts: overlay with HOW TO PLAY (controls, the five repairs,
tips) and SETTINGS (master volume, mouse sensitivity, view bob, render
quality); persists to localStorage, auto-opens on first visit, corner
badge + H toggles it.
- View bob now defaults OFF (playtest: reads as screen rumble to
non-Minecraft players); re-enable in settings.
- New hooks: PlayerController.setSensitivity, InputController.setSensitivity,
AudioEngine.setMasterVolume (safe pre-init), quality -> pixelRatio in main.
- Pause overlay suppressed while the menu is open; closing re-locks pointer.
Verified: menu renders over splash, both tabs, quality rescales the
framebuffer 2->1, settings persist, zero console errors.
