/* ---------- Hero ---------- */
/* Deliberately dark/immersive regardless of light/dark mode -- an aurora
   sky doesn't have a "light theme". Layers, back to front:
   1. dark scrim (keeps text legible over the photo)
   2. images/NuukDownlinks.jpg -- satellite downlink radomes, Nuuk. Swap
      this filename any time for a different hero photo; if the file
      doesn't exist the browser just skips this layer, no broken-image icon
   3. CSS aurora gradient fallback, always present
   4. a faint SVG overlay suggesting radio waves / orbiting electrons */
