 * - **idle** — slow breath, slow rotation, ambient halo
 * - **listening** — sonar ripples + faster pulse + boosted saturation
 * - **thinking** — sweeping arc + fast inner swirl + brighter shimmer
 * - **speaking** — rapid breath + bright core + extra saturation
 * - **asleep** — desaturated, dim, very slow drift
 *
 * No WebGL, no Canvas, no Rive — pure CSS layers + data-attribute
 * driven CSS variables. Renders identically in dev and prod.
