/* ==========================================================================
   hero.css — hero / brief auto intro
   The hero is a short 3D intro driven by space-scene.js. During the
   'initial' state the page shows only the 3D scene (no text yet). When
   the intro auto-transitions to 'revealed', the title fades in and the
   page becomes scrollable — the hero text stays visible as the user
   scrolls and naturally moves out of view with the hero section.
   No click, no skip button.
