Deploy Ladill Meet / deploy (push) Successful in 1m2s
Fix LiveKit connect flow and polish meeting room media UI.
Use the official LiveKit PHP SDK for tokens, harden client connect/publish timing, keep the Room outside Alpine reactivity, and replace emoji toolbar controls with synced mic/camera toggles and avatar tiles for audio-only participants.
