Detailed Description

Where an on-device-produced atlas lives: sink to write, pread to read back (DIP – an SDRAM memstore and an SD file both fit).

The import path writes the transcoded atlas through sink and registers the image over pread; both must address the same backing bytes. jof_memstore_t provides a matching RAM-backed pair.

Invariant: sink and pread address the same backing store.
