   青雲五號 QINGYUN No.5
   Single-residence listing. Bilingual (zh-Hant lead, English support).

   DESIGN SYSTEM NOTES
   - Vibe archetype: Soft Structuralism (white ground, large grotesk display,
     airy floating components, diffused ambient shadow). Chosen over Editorial
     Luxury because the brief mandates #ffffff / #111111 and because the warm
     cream + brass palette is the banned default for premium-property briefs.
   - Palette is MEASURED from the owner's own photograph of the house, not
     invented. See --stone-*, --accent below for the sampled source pixels.
   - One accent (the warm glow of the windows at dusk), one radius scale,
     one theme. No section inverts.
