/* ── Page background ────────────────────────────────
   Neutral graphite while idle; cross-fades to a vivid cyan → blue → violet
   aurora while running. The low-poly mesh sits on top in both states.
   Gradients can't be transitioned directly, so the states are stacked layers
   and only opacity animates. The aurora layer is oversized and drifts via
   transform, which stays smooth because it runs on the GPU. */
