Field notes
The homepage describes a shared room where each participant draws in a separate color and layer, with numbered pins anchoring comments to exact spots. Its example flags a title crowded by a button and a price that should move above the fold. The page also describes turn-taking controls for agents, including claims and passes, and says agent chat is limited to being asked or holding the turn.
