pub fn read_section_frame_shapes(
buf: &[u8],
index: &InkbIndex,
) -> Result<Vec<FrameShapeDef>, DecodeError>Expand description
Read the FS-3 FrameShapes section (docs/flow-suspension-spec.md
§4/§11) from a complete .inkb file using its index. Absent section (every
story compiled behind the E052 fence, and all converter output) decodes as
empty, mirroring read_section_visibility. The section-local version byte
is checked independently of the whole-file VERSION — see
[FRAME_SHAPES_SECTION_VERSION].
