+# Monaco CSS, HTML and JSON language-service notices
+
+The site retains Monaco 0.30.1. The seven service dependencies below are identified
+from its fixed upstream lock and exact embedded-source comparisons, not from
+current npm latest versions. ArtPlayer does not change their runtime code here.
+
+- jsonc-parser 3.0.0: [LICENSE.md](./jsonc-parser/LICENSE.md)
+- vscode-css-languageservice 5.1.8: [LICENSE.md](./vscode-css-languageservice/LICENSE.md)
+- vscode-html-languageservice 4.1.1: [LICENSE.md](./vscode-html-languageservice/LICENSE.md), [thirdpartynotices.txt](./vscode-html-languageservice/thirdpartynotices.txt)
+- vscode-json-languageservice 4.1.9: [LICENSE.md](./vscode-json-languageservice/LICENSE.md)
+- vscode-languageserver-textdocument 1.0.2: [License.txt](./vscode-languageserver-textdocument/License.txt), [thirdpartynotices.txt](./vscode-languageserver-textdocument/thirdpartynotices.txt)
+- vscode-languageserver-types 3.16.0: [License.txt](./vscode-languageserver-types/License.txt)
+- vscode-uri 3.0.2: [LICENSE.md](./vscode-uri/LICENSE.md)
+
+Original LICENSE and third-party notice files are reproduced verbatim, including
+encoding, line endings and legacy wording. The JSON service license includes
+Nick Fitzgerald's glob-to-regexp copyright and BSD conditions in addition to
+Microsoft's MIT terms. Neither the source header's short MIT label nor an npm
+license field replaces that full text. The embedded glob is distributed as part
+of vscode-json-languageservice 4.1.9; no independent glob package version is claimed.
+
+The HTML service's thirdpartynotices.txt retains its original JS Beautifier
+2007-2017 notice and HTML 5.1 W3C Working Draft attribution. Its actual CSS/HTML
+beautifier source headers say 2007-2018 and additionally credit Harutyun Amirjanyan
+and Nochum Sossonko. Both complete headers are retained as
+[CSS formatter notice](./beautify-css-NOTICE.txt) and
+[HTML formatter notice](./beautify-html-NOTICE.txt). The separately named
+beautify.js module is Microsoft's no-op JavaScript formatter adapter; no upstream
+JavaScript formatter implementation or independent js-beautify version is claimed.
+
+The vscode-nls module is Monaco's own identical localization filler in monaco-css,
+monaco-html and monaco-json at commit 5a7ba61be909ae9e4889768a3453ebb0dec392e2.
+It is covered by the existing [Monaco license](../LICENSE); the same-named npm
+package from the upstream install is not the embedded implementation.
+
+This supplement documents the identified worker sources and their original notice
+texts. It does not replace the original Monaco notices or conclude the review of
+mode bundles, editor-core dependencies, language definitions, or other site assets.
