Use this endpoint for targeted block edits. It applies id-based patches and keeps untouched blocks intact.
This endpoint does not perform full replacement. If you need full content replacement, use PATCH /assets/{assetId}/update with contentBlocks.
This endpoint is field-only (content, inline, meta). Use Apply block operations for structural transforms via turn_into.
