/* ============================================
   Feature 5 — Email Sign-Up Form
   Sign-up section with email and service interest.

   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
   - Ambient orbs mirror auth section for visual continuity
   - Reduced-motion safe (inherits from homepage.css)
