1//! Generic ISO 10303 STEP Part 21 and EXPRESS syntax infrastructure.
2//!
3//! The crate has no domain-schema dependency. It tokenizes bytes with spans,
4//! decodes physical-file strings, parses records into generic parameters,
5//! writes them back, partitions complete records, and offers a structural,
6//! explicitly partial EXPRESS declaration extractor.
