+/// Photo - JPEG ('jpeg'), QuickTime's Motion JPEG visual sample entry.
+///
+/// Unlike most video codecs, JPEG has no separate decoder configuration box:
+/// the quantization/Huffman tables and everything else needed to decode are
+/// self-contained within each JPEG-coded sample (baseline JPEG per
+/// [ITU-T T.81](https://www.itu.int/rec/T-REC-T.81-199209-I/en) | ISO/IEC 10918-1, the
+/// core JPEG bitstream standard), so this is just a [`Visual`] sample entry
+/// plus the usual optional extension boxes.
+///
+/// `'jpeg'` itself is a QuickTime-registered codec, not part of the ISO
+/// base media file format -- see its
+/// [MP4RA registration](https://mp4ra.org/registered-types/codecs) (spec:
+/// "QT") and Apple's QuickTime documentation on the
+/// [Photo Compressor](https://developer.apple.com/Mac/library/documentation/QuickTime/RM/CompressDecompress/ImageComprMgr/E-Chapter/5CompressorsSupplied.html),
+/// which each sample's JPEG bitstream conforms to.
