/* =============================================================
   Le Diplomate Café — Hero section
   Requires base.css. Hero layout, logo sequence, reveal animations.

   ═══════════════════════════════════════════════════════════
   FUTURE VIDEO SWAP — when the real brand video is ready:

   1. In index.html, replace the two <img> tags inside
      #hero-logo-sequence with:
        <video id="hero-video" autoplay muted playsinline
               poster="assets/hero-poster.jpg">
          <source src="assets/brand-intro.mp4" type="video/mp4">
        </video>

   2. In js/hero.js:
      - Remove the "V1 CSS SEQUENCE" block.
      - Uncomment the "VIDEO VERSION" block.
