PartyKit host is running

This URL is the multiplayer real-time server, not the Room Planner UI.

Use your Vercel site to edit floor plans. With a shared plan, the app opens WebSocket:

wss://room-planner-party.tsurbs.partykit.dev/parties/plan/<plan-uuid>

Set <meta name="room-planner-partykit" content="wss://room-planner-party.tsurbs.partykit.dev"> in the app’s HTML.
