/* ==========================================================================
   GridPiggy Energy — dark "flight-deck" theme on the Beusable design system
   --------------------------------------------------------------------------
   Content + information architecture : gridpiggy-hte5xvrk.manus.space
   Design tokens                      : Beusable / 뷰저블 (4Grit) OmD v0.1
   Art direction                      : near-future AI HUD — dark canvas,
                                        hairline instrumentation, cyan glow

   Token rules kept from the design system:
   - Rose (#ec0047) is the ONLY action colour; #ff1553 on hover.
   - Cyan (#00b7ff) is highlight / link — never an action.
   - Teal (#13a5bf / #16b5d2) and heatmap yellow (#f6e136) are data-viz only.
   - Full-pill CTAs, 4–5px radii on menu rows and tags, 20px on panels.
   - Depth still comes from hairlines and band contrast; glow replaces the
     drop-shadow ladder, and the one floating shadow token is kept for the
     floating controls (toast, sticky CTA).
