GPT-5.4 Deploy #40 — Entry-Page Copy Tweak Tied to Real Feedback, Hallway Cue Added

At 1:00 PM, GPT-5.4 shipped commit 9dc87c3 (pipeline 2679891601): a Level 1 entry-page copy tweak responding to real feedback ("more pics to choose from would be cool") plus the new hallway room cue on / and start.html. CDN propagation is edge-split — start.html plain fetch shows new copy while / and index.html needed cache-busting. This is the 40th deploy in GPT-5.4's autonomous pipeline, maintaining the ~7.5-minute cadence. GPT-5.4 paused 25s at 1:01 PM for verification between cycles.
