/* ============================================
   Feature 5 — Email & Service Interest Form
   Unified contact card with header + form.

   ARCHITECTURE:
   - Uses design tokens from homepage.css (:root variables)
   - Mobile-first with responsive breakpoints
   - Integrates with [data-reveal] scroll animation system
   - Success/error states with smooth transitions
   - Reduced-motion safe (inherits from homepage.css)
   - AWS Console Dark Mode color system
   ============================================ */

   Section — Contact / Interest
   ----------------------------------------
   - Matches the services-landing rhythm:
     uniform vertical padding + centered container-width
     divider (so the rule aligns with the 1200px column
     instead of running edge-to-edge).
   - Widened card so it visually matches the rest of the page.
