/* =====================================================================
   Ai20X design system v0.4
   Layout concept: institutional light pages (ruled columns, serif display)
   with dark-tech bands that carry the ecosystem diagrams.
   Taste dials: DESIGN_VARIANCE 6 · MOTION_INTENSITY 4 · VISUAL_DENSITY 4
   Rules applied: Taste (one button pair, one card style, one radius scale,
   one heading scale, no empty visuals, no scroll fade-ins, hero enters once),
   Impeccable (tinted neutrals, no grey on colour, no nested cards, no skipped
   headings), Emil Kowalski (custom ease-out curves, UI motion < 300ms,
   press 0.97, origin-aware popovers, faster exits, hover gated, reduced motion).
