 * inside a `Blob`-backed `Worker`, so it must not reference anything from its enclosing module
 * (including {@link GaussianSplattingSortWorkerCommand} — the command literals are duplicated here).
 *
 * The intended work for each message is selected explicitly via its `command` field:
 * - `positions`    set source splat centers (stride 4: xyz + 1).
 * - `partMatrices` set compound-mesh rig node matrices.
 * - `partIndices`  set compound-mesh per-splat rig node indices.
 * - `intervals`    set active source-splat ranges (flat [start0, count0, ...]); persisted across sorts.
 * - `sort`         sort the active splats for `{ worldMatrix, cameraForward, cameraPosition, depthMix,
 *                  cameraId, sortRequestId, rightHanded }` and post back a `sorted` result.
 *
 * @param self - the worker global scope
