/* ============================================================
   CONTACT — 06 / the closing section of the homepage.
   A direct-contact module (no form): an editorial left column +
   a contact "system" on the right (Email card, LinkedIn card,
   lower information panel), an empty right gutter column,
   and a full-width closing row.

   Shares the design language of the rest of the home
   (css/hero.css vars): dark ground, cyan glow, glass, mono
   labels, engineering grid, 100px pills. Reuses .glass and
   .live-dot from hero.css rather than redefining them.

   A reading section, not a live workflow: motion is a one-shot
   entrance only (js/contact.js toggles .revealed via
   IntersectionObserver, same pattern as cycle/showcase/
   interfaces/about).
