/* ===== Performance overrides (smooth + still alive) =====
   Strategy: keep ONLY the cheapest visual movement (the two .aurora radial

   real GPU work each frame:
     - filter:blur(32-40px) on body::after / .aurora-a / .aurora-b
       → blur is a per-frame full-viewport pixel pass, dominant cost.
     - mix-blend-mode:screen on body::before / .scanline-layer
       → forces compositing of full-screen layer each frame.
     - looping animations on body::before / body::after / .signal-mesh /
       .scanline-layer → not visually critical, skip the work.
   Result: page still feels alive (slow drifting glow) without the GPU
   thrash that caused scroll lag. Transform-only animations on layers that
   are promoted (will-change: transform) stay cheap. */

/* ===== Smooth + visibly alive =====
   Keep all decorative layers GPU-friendly (transform-only animations, no
   filter/blur, no mix-blend-mode), but make the movement actually
   *perceptible* by raising base opacity and widening the translate range.
   Layer rasterization happens once; subsequent frames are pure GPU
   compositor work, which is cheap regardless of the layer's gradient
   content. */
