/* Perf: these continuous, non-composited decorative animations repaint
   full-screen background layers every frame. They're barely perceptible on a
   phone but dominate the mobile main-thread budget (a top "Avoid non-composited
   animations" offender). Pause them on phones/tablets — the elements stay fully
   visible, just static. Desktop (already fast) keeps the full effect. Only the
   safe-to-freeze ones are listed (SVG stroke-dash reveals are excluded, since
   freezing those would leave the paths hidden). */
