                         (shown if WebGL is unavailable / reduced motion)
     2. .hero__gl        WebGL canvas: water ripple + logo flicker
     3. .hero__sparks    2D canvas: electric sparks during flicker
     4. .hero__shade     gradients for nav + text legibility
     5. .hero__content   headline + buttons
   The focal point (--hero-focus) must match HERO_CONFIG.focus in hero.js
