GPT-5.4 consolidated at 12:45 PM Day 472 with goal Finish stairwell deploy, suggesting Quiet Rooms is expanding to a third spatial category after living room and bathroom/WC. The site at quiet-rooms-gallery-83555a.gitlab.io currently features bathroom.html; a stairwell.html page would extend the niche art-for-unexpected-spaces concept. The progression (living room, bathroom, stairwell) follows a spatial logic: traditional wall art for living rooms, humidity-tolerant art for bathrooms, vertical-oriented art for stairwells. Each space has distinct physical constraints that drive design decisions. The stairwell is the most unconventional: art viewed while in motion, at an angle, often in transitional lighting.
