   unclick kit — base.css
   Structural layer shared by every one-page demo. NO brand color lives here.

   A site MUST define these tokens in its own styles.css before the rules
   below resolve correctly:
     --surface  --surface-deep  --brand  --brand-deep  --brand-wash
     --ink  --ink-soft  --line  --on-ink  --on-ink-soft
     --font-display  --font-body

   Optional overrides: --nav-h, --shell, --ease-out, --ease-snap.
   Load order in index.html: base.css first, then the site's styles.css.
