Module canonical 

Canonical-form byte primitives — no_std, no_alloc, slice-in / slice-out.

Every UOR-ADDR realization that touches a published canonical form routes through this module. The module is shaped to be liftable upstream as a uor-prism feature without surface churn — the signatures already match prism’s &[u8] → &mut [u8] → usize discipline.

Modules

• hex — lowercase-hex byte-emit. Produces the 64-byte ASCII suffix crate::label::AddressLabel carries.
• nfc — UAX #15 Unicode NFC normalizer. Streaming three-stage decompose / canonical-reorder / compose. UCD tables vendored at nfc::tables (version pinned in nfc::UCD_VERSION).

Every public function in this module is no_alloc and no_std. No path through the module performs heap allocation, locks, or syscalls.
