/* KNUENCE™ website design system v1.0 — components and layout.
   Depends on knuence.tokens.css (generated). Single-class selectors throughout so specificity stays flat.
   Rules carried from the Brand Identity Manual, Edition 1.0:
   – the brand gradient is used on graphics only (the K, rules, edges), never on text;
   – Knowledge Cyan is never used for text or controls on light backgrounds;
   – interface motion is 150–250 ms, opacity and position only, and stops under prefers-reduced-motion. */
