/* ==========================================================================
   Platform design tokens — v3.
   Design system: design-system/platform-core/MASTER.md (candidate C,
   "Scoreboard Neon", picked 2026-10-05): black with a green cast, one
   matrix-green accent, terminal radii (3/4/6px), mono display type,
   a single glow effect. Typographic UI — marks are letters, status is
   words; there is no icon system.
   Every accent derivative is computed from the single --accent via
   color-mix (see the @supports block below), so the operator's
   Settings.accent_color retints the whole system from base.html's
   inline `:root { --accent: … }` override.
   Dark-only.
