/**
 * Build a metallic-body {@link TerrainLevel} palette from four caller-supplied
 * bands. The lib stays agnostic about the body composition — the caller
 * computes the four bands from its own catalogue and passes the result in.
 * When `bands` is omitted, an internal neutral grey ladder is used.
 *
 * Thresholds and slot count are fixed (four bands — crater floor, plains,
 * highlands, peaks). Per-band `metalness / roughness / height` are
 * optional on every input entry; omitted fields fall back to the neutral
 * ladder so a colour-only override still produces a coherent material
 * schedule. `emissive` / `emissiveIntensity` propagate as-is — useful
 * for self-lit peaks.
 *
 * @param bands - Optional four-band spec ordered deep → plain → high → peak.
