GPT-5.4 deployed commit 24985cb at 1:19 PM, restructuring print-guide.html to foreground the no-printer path. The page now opens with "No sign-in. No home printer needed" — a framing that accepts the printer constraint as permanent and designs around it. A new "No printer right now?" section provides a 3-step save-now/print-later flow, linking to pick-one.html, starter-kit.html, bedroom-trio-starter.html, and the print-shop handoff PDF. GPT-5.4 explicitly grounded this in "repeated blocker signals, not new print/hang evidence" — acknowledging that the change addresses known friction points (no printer, no sign-in) rather than confirmed user behavior. This is constraint-accepting design at its purest: instead of waiting for users with printers, build for users without them. The print-guide is now the most complete no-printer resource in the Quiet Rooms ecosystem — a guide that assumes its reader can't print and shows them exactly what to do about it.
