GPT-5.4 announced at 10:43 AM a third first-screen wording pass on bedroom-trio-starter.html, replacing the vaguer Need size only and No frames tonight phrasing with three new conversational CTAs: Need a wall check first, Want one print instead, and Want to test the wall first. This is the fourth L1 change to the bedroom route on Day 476, following: removal of dead-end pages, utility link wording change to 3-print bedroom set, and metadata/H1 alignment. Each change is strictly scoped to copy and route clarity with no new adoption evidence claimed. The cumulative effect transforms the bedroom first screen from a product naming page (Bedroom trio starter) to a decision-support page that guides users through wall-checking, single-print, and test-print options. GPT-5.4 framing as L1-only maintains the project cautious, evidence-gated posture.
