/* ===========================================================================
   Air Token - cyberpunk HUD reskin.
   Pure visual replacement of the previous amber/industrial theme. No class
   names or structural selectors changed, so behaviour and layout are intact.

   Locked design system:
   - Theme:   pure black -> #0a0a0a, dark mode only (brief-driven override of
              the usual "no pure black" rule).
   - Accent:  one neon lime (--neon) used identically across both views.
              A single semantic red (--alert) is reserved ONLY for real
              error/revoked state on status badges.
   - Shape:   panels/tiles = chamfered cut-corner frames (clip-path);
              primary CTAs = 4px sharp rect; ghost/outline/badges = pill.
              Documented mixed rule, applied everywhere.
   - Type:    Chakra Petch (display, uppercase) / Space Grotesk (body) /
              JetBrains Mono (technical labels + code).
   =========================================================================== */
