   HERO — VIDEO BACKGROUND
   
   Structure:
     .hero-bg   — outermost: overflow:hidden, establishes stacking
     #hero-video — absolutely positioned, fills container, z-index 0
     .hero-bg::after — gradient overlay, z-index 1
     .hero       — flex column, pushes content to bottom, z-index 2
   
   VIDEO FALLBACK LOGIC (handled in JS):
   On slow/metered connections (saveData or 2G/slow-2G) the JS
   removes the <source> element before the browser fetches it.
   The CSS background-image on .hero acts as the static fallback
   — it is always present and visible until the video's first
   frame paints, which also covers the no-JS case.
