A familiar playfield—shared bowl, clear stats, usual buttons. The quantum twist is atmosphere: soft grid, spin reference, P31 colors.
This page is local-first: you choose a shared room string for your household—it is not public matchmaking. Stay in the loop on which room name is in use.
Run two things on the machine that serves this page (repo root):
npm run demo — static server (port 8080)
node spikes/mock-ws-server/server.js — WebSocket (port 8082, or set MOCK_WS_PORT)
Then open a second browser or tab with the same room and a different name. Use Copy invite link below when family play is active.
Quick name tags (same house: pick a room first, e.g. living-room):
Same counters and links you’d expect in a sim—the “quantum” layer is look-and-feel, not different rules.
