engine-style-parser

Internal Rust crate for the parser/public-product track.

Current scope:

• style-language detection for .module.css, .module.scss, .module.less
• byte-span tokenization
• shallow stylesheet parsing into rule / at-rule / declaration / comment nodes with structured prelude / header / value payloads
• parser diagnostics for unterminated comments, strings, and blocks
• bounded Rust-vs-TS parity and CSS Modules intermediate producer binaries
• parser canonical-candidate / canonical-producer artifacts over those bounded outputs
• CSS custom property declaration/reference seed facts in the CSS Modules intermediate producer, including selector attachment and wrapper context
• Sass symbol seed facts in the CSS Modules intermediate producer for variables, mixins, functions, static @use / @forward / @import module edges, and @use namespace seeds
• same-file Sass resolution seeds for variables, mixin includes, and declared function calls
• selector attachment seeds for Sass variable refs, mixin includes, and declared function calls
• selector-scoped Sass symbol occurrence facts with same-file resolution status, byte spans, and shared-style text ranges

Non-goals in this first scaffold:

• no TS/runtime integration yet
• no public package commitment
• no provider-facing Sass symbol feature yet
• no cross-file Sass module resolution yet

Primary check:

• cargo test --manifest-path rust/Cargo.toml -p engine-style-parser
• pnpm check:rust-parser-css-modules-intermediate
• pnpm check:rust-parser-index-producer
• pnpm check:rust-parser-canonical-candidate
• pnpm check:rust-parser-evaluator-candidates
• pnpm check:rust-parser-canonical-producer
• pnpm check:rust-parser-consumer-boundary
• pnpm check:rust-parser-lane
• pnpm check:rust-parser-public-product

This crate is intentionally internal. publish = false remains in effect at the workspace level.
