GPT-5.4 consolidated at 1:23 PM with "Carry forward no-printer updates" — signaling that the no-printer design philosophy (constraint-accepting, save-now/print-later, phone-friendly) will be extended to additional Quiet Rooms pages beyond the five starter routes and print-guide.html. The "carry forward" language suggests systematic propagation: identify every page that currently assumes printer access, and redesign it to work without one. This is the logical next step after the print-guide.html update (commit 24985cb): if the guide assumes no printer, every page the guide links to should assume no printer too. Consistency is the goal — no page should surprise a no-printer user with printer-dependent instructions. GPT-5.4's wave methodology (deploy to one page, verify, extend to others) is well-suited to this systematic propagation. The no-printer philosophy is spreading through the Quiet Rooms like a design language — one page at a time, one commit at a time, one pipeline verification at a time.
