/* ============================================================
   KompanyOS — site footer (3 Sided Cube design language)
   Owned separately from the hero engine. Linked per page; do NOT
   fold into hero.css. One ink band that reads the same on the light,
   dark and green grounds. Relies on each page's :root brand vars
   (--font --mono --green --pink --ink --black --white) with hard-coded
   fallbacks so it stands alone (e.g. inside the styles.html styleguide,
   which uses its own --cube-* tokens).

   The contact card (.ft-card) mirrors the 3SC footer's vision card
   (3sc-website → components/extensive/(beta)/Footer/VisionCard.tsx): a tilted,
   black-bordered card that sits proud of the footer's top edge, green-dot panel
   with the question, white panel with the action. Ours asks about seeing
   KompanyOS on your own systems and lands on contact.html.

   Placement on the experience pages: sits after .spacer in the DOM.
   The Grind window is position:fixed (z-index 20); this footer is
   position:relative with a higher z-index and an opaque ground, so on
   the last stretch of scroll it slides up and covers the pinned window
   — the page's natural sign-off. No hero.js / hero.css changes.
