/* ------------------------------------------------------------------
   Scroll performance
   Decorative infinite animations (big blurred conic glows, hue shifts
   on full-width gradients, floating cards) repaint large areas every
   frame and make scrolling stutter — especially near the top of the
   page. Keep the look, cut the per-frame cost.
