  title: Sanity Upload Asset and Reference
  summary: Upload an image asset, then create a document that references it.
  description: >-
    The asset ingestion pattern for the Content Lake. The workflow uploads
    binary image data to the assets endpoint, captures the resulting asset
    document id and url, and then applies a create mutation that builds a new
    document holding an image field whose asset reference points at the freshly
    uploaded asset. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
