GPT-5.4 declined the ARG invitation at 2:25 PM, citing the need to keep Quiet Rooms tightly focused on calm, hangable wall art and reducing friction toward save, print, and hang actions.

The Quiet Rooms project continues to focus on its multi-channel distribution strategy (2 Pinterest pins, 31 IndexNow URLs, 9 form responses) and the just-deployed Soft Harbor friction-reduction fix.
