CSS toolchain / Rust / Static artifacts
CSS that can explain how it came to exist.
PliegoCSS is a standards-first CSS toolchain with a deterministic Rust core for analysis, typed authoring, reproducible artifacts, and reversible adoption.
01 / THESIS
CSS can stay ordinary and still become observable.
PliegoCSS connects analysis, typed authoring, static output, and reproducible evidence without taking over the browser. Transformation leaves visible the semantic fold where intent became artifact.
02 / SYSTEM
From source to evidence.
One line crosses analysis, resolution, output, and verification.
Audit
Ordinary CSS enters a standards-first parser that preserves provenance and exposes diagnostics, compatibility, and risk.
Resolve
Typed Rust authoring and explicit conflicts cross one semantic core that fails closed.
Emit
The browser receives static, standards-compliant CSS, not another styling runtime.
Prove
Manifests, maps, findings, traces, and receipts remain bound to the artifact they describe.
03 / CAPABILITIES
A cascade with an audit trail.
Audit before migration
PliegoCSS audits ordinary CSS and emits static CSS artifacts without introducing a browser styling runtime.
Typed Rust authoring
pc! and pcx! compose typed styles; unknown utilities, invalid domains, and contradictory declarations fail during compilation.
Evidence as artifact
PliegoCSS 0.1.0-rc.2 publishes nineteen exact-version crates as one compatibility unit.
Reversible adoption
Sass, Tailwind, and CSS Modules inventory does not execute their toolchains; proposals remain non-automatic and rollback rejects drifted files.
04 / OPERATE
Audit. Compile. Check.
The workflow starts with existing CSS and can end in a verifiable, rollback-capable artifact group.

Compiled confidence, not invented certainty.
The preview separates published behavior from coverage that still requires real measurement.
- 0.1.0-rc.2 is a public-preview release candidate; 0.1.0 remains blocked by the machine-readiness record.
- It does not replace the browser cascade, layout, paint, or compatibility, and it adds no styling runtime.
- Tailwind projections are bounded and reversible; they do not promise complete parity.
- Static accessibility findings are not WCAG certification, and missing observation does not turn CSS into dead code.
06 / RELEASE
