/* =====================================================
   IMAT Quest — Lead form  (css/lead-form.css)
   Added 2026-06-26.

   On-brand "Get matched with a mentor" lead-capture form.
   Single-column (best form-conversion + mobile-first).
   Sits between the colophon CTA and the footer.
   Reuses: .container, .btn .btn-primary, .reveal (from style.css).
   References design tokens from css/tokens.css — no hardcoded values.
