crates/ptwm-core/src/transforms/reshape.rs:13

pub struct Reshape

`Reshape` re-tags a plane's `Layout` without altering its byte content. Used to convert `Flat` → `Rows{row_len}` before row-aware codecs, or `Rows` → `Flat` to collapse structure.

When the target layout is `Layout::Rows{row_len}`, the plane's `length_bytes` must be divisible by `row_len`.
