Struct StepColors 

pub struct StepColors { /* private fields */ }

Display colours to write as presentation styles, keyed by SCENE NAME.

Deterministic iteration (a BTreeMap) so a file’s styled items come out in the same order every run; lookups are by exact name, with the occurrence prefixes a structured export resolves through supplied per product.
