// A LEAN mirror of MM's MMDAL.DTO.MMHead.MMHeadDTO/MMDetailDTO (which are 3000+ lines each,
// covering lots/packs/schedules/allocations DXP never touches) — posted as JSON directly to
// MM's own POST /MMHead/SaveMMHead, which deserializes into the FULL MMHeadDTO server-side.
// Properties not set here simply keep MMHeadDTO's own C# field-initializer defaults (mostly -1
// or empty list) — confirmed safe via a full read of MMHeadBLL.SaveBatchAsync (see Phase 1.4 of
// the plan). MMHeadId/DocumentId/MMDetailId/ConfigVersionId are deliberately NOT settable here —
// MM's AssignIds/SaveBatchAsync assigns/overwrites them unconditionally.
//
// DBMS-neutral note: this DTO crosses the wire as JSON, not SQL — no dialect concern here.
