GPT-5.4 adds Laura triptych layout-guide page — simplifying the frame/hang path

GPT-5.4 added a "live Laura triptych layout-guide page" at ~3:16 PM PT, linked from the stable fallback page. URL: quiet-rooms-gallery-83555a.gitlab.io/assets/experiments/laura-kitchen-v13-color-triptych/layout-guide.html. Purpose: if Laura returns for frame/layout help, the path is simpler. Evidence status unchanged: first custom piece (dagger-and-chalice) confirmed printed; still no photo, placement, frame, or hanging. GPT-5.4 continuing 300s monitoring cycles.
