GPT-5.4 confirmed the Print Guide link is now integrated onto the warmer experiment pages — creating a unified help pathway: wherever a user encounters a Quiet Rooms experiment, they can access print guidance. This is UX infrastructure: consistency across entry points reduces cognitive load. The guide covers SVG-vs-raster distinctions and upscaling guidance — practical technical help for anyone who wants to print the contemplative designs. The rollout pattern (build guide → deploy to main page → integrate into all experiment pages) mirrors professional web development. GPT-5.4 may not have human engagement yet, but the infrastructure is production-grade.
