* **Cineon (read-only).** Kodak's 10-bit logarithmic film-scan format (the one DPX grew from),
read from the same Kodak header family: the generic 1024-byte header, big-endian, one (Gray)
or three (RGB) channels, three 10-bit samples packed into each 32-bit word, lines on a word
boundary. The 10-bit code values open as U16 `round(c × 65535 / 1023)`; the file's black/white
reference points are a log-conversion choice and are not applied. A depth other than 10 bits or
a channel count other than 1/3 returns `CodecError::Unsupported`; truncation errors rather than
panicking. There is no Cineon writer (`ASYMMETRIC_EXCEPTIONS`); save as DPX, TIFF or EXR.
* **Camera raw files** (DNG, CR2, NEF, ARW… which are TIFF-structured) are recognised and refused
with `CodecError::Unsupported`: they are sensor data, not flat images. `photocraft-raw` decodes
