/**
 * Derives lib shader params from a BodyConfig + optional visual variation.
 * When variation is provided, all shader parameters are covered.
 * When omitted, physics alone drives all params.
 *
 * Rocky bodies read their palette anchors from `config.terrainColorLow` /
 * `config.terrainColorHigh`. Callers compute the anchors themselves and
 * write them back onto the config before calling this function (see the
 * playground's `deriveTemperatureAnchors` for a temperature-driven default
 * reference implementation).
 *
 * Per-type assembly (defaults, special fields like `temperature` for stars)
 * lives in {@link strategyFor} — this function is now a thin wrapper that
 * resolves the seed and forwards to the strategy's `buildShaderParams`.
 *
 * @param config    - Body configuration.
 * @param variation - Optional deterministic visual variation.
