Black-box derived layout: 0x4000-byte chunks stored rotated by 0x1ff8, 16-byte LE blocks read LSB-first (10x12-bit or 9x14-bit samples). Sensor borders, CFA code, per-channel black, linearity limit, WB levels, ISO; JpgFromRaw preview via a generic undefined-tag JPEG candidate. The quantised raw format 4 reports Unsupported (documented gap). Adds a rawdump debug example. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

//! followed by `width × height × cpp` little-endian `u16` samples, for analysis in external tools.
