- Click a rock to open a world-anchored mining popup (Mine/Stop/Cancel)
- Mining state machine locks the ship during the ~1.5 s arm extension, then fires an animated beam with ore motes, shock rings, sparks, and periodic surges
- ESC breaks the beam or closes the menu; outside clicks dismiss without flying
- Generalize the top-center console toast so discovery, tether, and mining calls share one slot
- Add a "mining" SFX entry (system-scan.mp3) and update preload/test to cover all configured sounds
- Ship a headless browser test (dev/mining-test.*) that drives the full arm sequence through the real input pipeline
