/* tasteHQ shared top-nav — used by gallery, spec, eval, scorer, demo.
 *
 * Self-contained defaults. Pages can override via CSS variables on `:root`:
 *   --nav-bg, --nav-border, --nav-hover, --nav-active-bg, --nav-font, --nav-mono
 *
 * Defaults use color-mix() against currentColor so the nav blends with the
 * page's existing palette without per-page declarations. */
