/* ==========================================================================
   VibeSet — design system (minimal).

   One stylesheet, no framework, no external fonts. Two themes driven by
   [data-theme] on <html>: "dark" (default) and "light"; the preference is
   "system" unless the user picks otherwise.

   The direction is minimal: a single accent colour used sparingly, flat
   surfaces (a 1px border plus a faint tint, never blur or translucency),
   no colour ramps, no decorative backdrop layers, no glow. Hierarchy comes
   from type size, weight and spacing; monospace is kept for numbers,
   model ids, coefficients and code because it genuinely reads better.

   Sections, in order:
     1. Tokens          6. Buttons & forms      11. Landing: coding ranks
     2. Reset & type    7. Tables               12. Landing: calculator
     3. Chrome          8. Badges               13. Landing: FAQ & misc
     4. Layout          9. Model cards          14. Toasts
     5. Stat cards     10. Landing: hero        15. Motion & print
