Module lip 

LIP binary lip-sync support. LIP binary reader and writer.

LIP files store lip-sync animation keyframes for voiced dialogue. Each keyframe maps a timestamp to a viseme (mouth shape) index.

Shape of the container

A 16-byte header and a keyframe array directly after it. No offsets, because nothing here needs to point anywhere.

The five-byte keyframe stride is load-bearing rather than incidental: the engine animates straight off the raw file buffer instead of parsing the array, so the entries are packed with no alignment padding and adding any would be read as garbage rather than as a variant.

Byte-level field maps live in docs/src/formats/audio/lip.md, with the engine’s own load sequence.
