Package compile lowers a parsed Quill module to a single deterministic Go source file whose render function writes the template's output to an io.Writer.

Package covercore holds the engine-internal instrumentation core behind template coverage: the region identity model, the RegionKind vocabulary, the mutable region map, and the Hit / Seed record-and-seed logic the interpreter drives.

Package interp is Quill's tree-walking renderer.

Package jsonval converts decoded JSON into Quill runtime values.

Package lex is Quill's lexer: a byte-oriented, two-mode (TEXT/CODE) scanner for the @-sigil default statement form described in spec 01-language-reference Section 1, spec 02-grammar Section 2, and design/lexical.md.
