/* MeriTec design system — light USA theme, flat surfaces (Adam, 2026-08-06 partner-feedback
   refresh: decorative gradients and decorative red removed platform-wide; 2026-07-20 Type Lab R2:
   Inter universally). 2026-08-10: the whole blue story moves to one vivid royal (#0249c7,
   sampled from the partners' own reference), flat — the rail is now a solid fill, not a gradient,
   and the navy family collapses into the royal (navy #063b9e, navy-2 #0249c7, navy-3 #2c6fe2) so
   rail, hero, instructor card, primary buttons and progress fills all read as the same blue. The
   canvas lifts to #f7f8f9. Contrast re-checked: white on the rail 7.55, the blue as card text
   7.55, the active pill 4.69 — all pass AA. Everything else sits flat: a
   light canvas, cards that lift
   by border + shadow, one royal family beside the rail. Red is a signal only —
   danger, over-cap, unread — never decoration. Frosted glass survives where it overlays real
   content (menus, modals, scrim); bright top edges = light catching the material, size-specific
   tracking, instant press feedback, hover only on real pointers. Solid fallbacks:
   reduced-transparency + no-backdrop-filter. Async has three visible states: every control that
   triggers async work reads as idle, then in-flight and inert, then settled. Nothing may
   double-fire. */
