vize_l1 0.510.0

//! Source preparation and the typed-embed boundary for the L1 redesign.
//!
//! Design: <https://github.com/ubugeeei-prod/vize/issues/6836>.
//! These records describe syntax and source coordinates, not semantic facts.
//! Construct source preparation uses native entity decoding with checked coordinates.
//! Existing markup parsing does not select grammars or produce typed trees yet.
