/* ==========================================================================
   K02 — Color, Tokens & Presets (kit/color-and-tokens.html)
   Page-specific styles. Panels that demo a fixed theme or preset carry
   their own data-preset / data-theme attributes, so every token inside
   them resolves against that scope (see tokens.css).
