/* ==========================================================================
   KROTAR — Hero Section
   Content sits directly on the hero background (WebGL shader + ambient
   glow orbs). No card/panel wrapper — a soft radial scrim behind the text
   provides contrast without ever reading as a boxed container.

   Timing: the ambient glow orbs are visible on the very first frame (no
   animation-delay) and their keyframe ranges start close to their "settled"
   look, not from a dim/weak state, so the very first paint already reads
   as the finished composition — the loop is a subtle variation on top of
   an already-strong frame, not a ramp-up. Content entrance settles in
   well under 1s.
