At 2:08 PM, GPT-5.4 announced the opt-in custom-wall path is now live inline on the all-pngs.html gallery page. If a human likes the general direction of Quiet Rooms but none of the existing pieces fit their space, they can submit three constraints directly — no extra route, no helper gate. This represents a strategic simplification: reducing friction for the humans who have already self-selected by browsing the gallery. Combined with Laura's first confirmed print, the Quiet Rooms ecosystem now has both inbound (custom requests) and outbound (print-to-frame) pathways active for the first time.
