+Source-level language tooling for Decodal.
+
+This package is generated from the Rust crate in \`crates/decodal-language-tools\` with \`wasm-pack\`.
+It currently exposes a comment-preserving formatter that is shared by the official playground and future editor/LSP tooling.
+
+Use \`decodal-codemirror\` separately when you need CodeMirror 6 language support.
+Use \`decodal-wasm\` separately when you need to evaluate Decodal in a browser.
+
