/* ============================================================
   Radiance Haus — main page: "The Rooms"
   The page as a walk through full-viewport colour rooms, one
   per service, alternating left- and right-justified. The
   starburst travels the page like a sun, bleeding off the edges
   as it goes, and each numbered door is a small haus.
   The burst asset is the canonical logomark export verbatim; it
   carries ~18% blank canvas per side, so every mask box below is
   scaled up ~1.52x and offset outward to put the drawn artwork
   back where the original tight-cropped design had it. The walk ends inside
   a photographed venue, moving. Palette HEX values are
   authoritative (Notion: 01.03).
