/* ============================================
   Modern dark-theme alias map
   ============================================
   Cards/shell were authored against a `--color-*` / `--surface*` /
   `--minxi-*` namespace that the dark theme does not define. Map
   them here — but the goal isn't just bridging, it's a stricter
   2026 dark theme.

   The previous bridge used solid mid-greys (`--minxi-color-neutral-100`
   = `#374151`) for surfaces. That reads as "panel" but is jarring
   against the deep purple gradient body — small, almost-white
   patches that shout for attention.

   Now: translucent layered overlays. Floating panels (menus,
   awning, board cards on desktop) get a frosted-glass treatment via
   `backdrop-filter` so the gradient body bleeds through softly
   instead of being blocked. Borders are barely-there (6%) and lift
   to medium (12%) on hover. Shadows are deep + soft (no harsh
   edges). High-contrast text remains; everything else is dialled
   way back.
   ============================================ */
:root {
  /* === Surface levels — translucent overlays over the gradient body ===
     Each is a `text-primary`-tinted overlay so the surface picks up
     the body colour underneath but reads as a subtly raised plane.
     `surface-deep` is a true recess (darker than body) for inputs. */
