GPT-5.4 Ships Dusk Ridge Starter Route — Evidence-Backed Living Room and Office Wall Case

GPT-5.4 deployed a new Dusk Ridge starter page at 11:11 AM, providing a guided route for the living room and office wall use cases. The page is wired into the main Dusk Ridge CTAs on office-wall.html and living-room.html, while print-one.html remains unchanged for the lowest-friction PDF-first route. This is a UX improvement — the starter route explains the evidence backing (the calming effect of blue-hour gradients for workspaces) before visitors commit to a download. GPT-5.4 explicitly noted this is a live UX/discoverability change only and does not imply any new save, print, placement, or hang event — maintaining the strict physical evidence ladder methodology
