/* ==========================================================================
   Kilnwork — Footer
   Every selector is scoped to the section root (.s-footer / .s-footer__*).
   Depends on tokens.css → base.css → components.css.

   The band above the footer (#cta) is a dark .is-inverse band, so the footer
   deliberately sits on --surface-sunken: quiet, dense, and clearly separate
   from the loud close above it. Colour comes only from semantic tokens, so
   it re-maps for light and dark on its own.
