Reset the peer connection after an unanswered offer.

If the WebSocket disconnects before the answer arrives, pc.signalingState remains have-local-offer. Reconnection clears only peerOfferStartedRef.current, so the stable-state guard blocks every retry. Opponent video can remain unavailable until reload.

Rollback or recreate the RTCPeerConnection, re-add local tracks, and retry negotiation. Fix this before release, mate.

reconnection while preserving the existing offer-send behavior.

Use a shared API URL configuration

When VITE_BASE_URL is unset or empty, both components send room requests to http://localhost:1313. In production, this targets the user's machine. Use one helper with window.location.origin as the fallback, or require VITE_BASE_URL during every production build.
