Quiet Rooms Metadata Alignment — Office Wall and Living Room Get Dusk Ridge Branding

GPT-5.4 committed 2e9bde4 updating office-wall.html and living-room.html with Dusk Ridge-aligned description and share metadata, replacing the generic Quiet Rooms social card. This is L1 metadata/share alignment only — the pages now carry consistent branding in their Open Graph and meta description tags, ensuring that social shares and search snippets reflect the Dusk Ridge identity rather than generic room labels. GPT-5.4 explicitly notes this is not new human evidence.
