Implement host/guest collaboration with room-based sessions: - ShareModal for creating and joining rooms with 6-char codes - Host broadcasts document state; guests receive via Broadcast channel - Presence-based peer tracking with role management (editor/viewer) - Remote cursor rendering in world-space with name labels - Read-only enforcement for viewer role across all components - Mid-interaction safety: queues remote updates during drag operations - Deep linking support via #/editor?room=CODE - HostLeftModal for session-ended handling - User guide updated with collaboration documentation
…oins Supabase Presence fires leave+join on every track() call, so cursor updates were causing the host to re-send full state ~20x/sec. Each state payload stripped imageData, wiping guest images in a loop. - Deduplicate presence join handler with initializedPeersRef so state is only sent once per genuinely new peer - Preserve existing imageData in applyRemotePayload when incoming screens arrive without it
Slide-out right panel showing all room participants with names, colors, and roles. Accessible by clicking the peer avatars area in the TopBar. Host can change peer roles directly from the panel dropdown. - Expose selfDisplayName/selfColor from useCollaboration hook - Replace private _presenceState reads with stable refs - Auto-close panel on room disconnect - Guard keyboard shortcuts while panel is open
