Tailwindcss Foundation

Use when porting Tailwind CSS v4 compiler mechanics — the `compile()`/`compileAst()` incremental build kernel, `@theme` design-system ingestion and resolution, candidate parsing/compilation and its deterministic sort ladder, or the variant application protocol — into another utility-CSS engine or a host integration (Vite/PostCSS/CLI driver). Source code and direct tests are ground truth; references carry decisive excerpts and graph retrieval.

tailwindcss: v4 core compiler foundation

Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is historical, revision-pinned evidence rather than timeless guidance. Current project source, tests, requirements, and runtime behavior outrank this projection and decide what ships.

Provenance and revision

Source record: tailwindcss; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: main@90f8ff41c8e2a4d17bc76921e23e9d672123da76.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Incremental build kernel; Candidate sort ladder; Design-system memo lattice; Variant application protocol; Theme namespace reset; Theme resolve var/inline; @theme ingestion; Candidate parse pipeline.
Scope and retrieval questions: references/index.md#use-this-for.
Complete capsule chooser: references/index.md#load-the-matching-source-dump.
Detailed grouped map: references/index.md#capsule-map.
Source limitations and portability boundaries: references/index.md#boundaries.

Retrieval

Open the index, choose one capsule matching the active question, and load only that capsule. Revalidate its cited source and revision before relying on it. Do not bulk-load the inventory, treat historical claims as current truth, or apply this foundation as a procedure.
