/* open.gismo guided setup — design session, 2026-08-27.

   Base tokens follow the obot report family (executive overview 2026-07-21,
   goal atlas 2026-07-24, platform gap analysis 2026-07-25) and inherit the
   same three-state light/dark contract: the complete light palette on bare
   :root, the dark palette redefined under prefers-color-scheme guarded
   against an explicit light choice, and again under [data-theme="dark"] so a
   toggle wins in both directions.

   The walkthrough page overrides these with open.gismo's own espresso theme
   (see walkthrough.css) because a mock of a product should look like the
   product, not like the page it is printed on.

   Every state carries a glyph AND a word. No colour-only status anywhere.
   Nothing is fetched at view time: no CDN, no web fonts, no build step. */
