/* Ora's one design system (LA-1896). The tile, the room page and the owner's panel all
   load this file and keep nothing of their own but layout.

   The palette comes from the tile art (LA-1895, assets/tile-art/): charcoal, cream and
   purple. Purple marks Ora and real state only: the live
   mark, the main action, a link. Red is ink, and only ever a stamp on paper or a failure
   line. Cards are paper in every theme, since a card is a document Ora quoted.

   The tile is always dark: it sets data-theme="dark" on <html>. The room page and the
   panel follow the viewer's light or dark setting unless the page sets data-theme.

   Every text colour below passes WCAG AA (4.5:1) on the surface it is used on. The
   ratios were computed on 2026-10-08 and are in the LA-1896 entry of docs/DECISIONS.md.
   Change a colour, and check its ratio again. */
