/* ============================================================================
   Gemisfera UI — shared design system
   ----------------------------------------------------------------------------
   Quiet, Apple-minimal: one typeface (Vela Sans, the same face the device
   draws), near-neutral surfaces, hairline separators instead of boxes, soft
   depth only where something is raised, and generous space doing the grouping.

   Token names still mirror shadcn/ui (OKLCH) so React components could drop in
   without remapping. Vanilla CSS: the portal has no build step and is rsync'd
   and served raw, including to the Pi.

   Palette rules (see PRODUCT.md):
     · Neutrals are near-neutral (≤0.006 chroma). The installation's colour is
       the device, not the chrome around it.
     · Green is reserved for LIVE STATE. A green pixel that doesn't encode state
       is a bug.
     · Focus is cyan, never green — focus can never be misread as "live".
     · Text tokens are ≥7:1 on --background/--card except --muted-2 (AA,
       peripheral metadata only).
