RUST-NATIVE CSS TOOLCHAINPUBLIC PREVIEW / MEDELLÍN / 2026

Style manifests

Trace source intent into emitted bytes.

Manifest schema 5 connects source origins, semantic assignments, final selectors, physical declarations, and CSS ranges.

Identity chain

StyleId identifies canonical semantics. Class identity, theme identity, configuration, and final CSS hash bind that style into one build.

pliego-cssc compile --source src --manifest dist/app.manifest.json \
  --manifest-version 5 --output dist/app.css

Physical lineage

Generated custom properties and synthesized declarations retain contributors, importance, conditions, selector, property, value, and output byte range.

Request the schema you consume

Schema 3 supports style manifests, schema 4 adds reachability ownership, and schema 5 adds closed physical tracing. Consumers must pin their contract.
