Source: node_modules/marked/lib/marked.esm.js — marked v18.0.6, the version the repo pins ("marked": "^18.0.6" in the root package.json).
License: MIT — copyright (c) 2018-2026 MarkedJS, (c) 2011-2018 Christopher Jeffrey. The attribution header at the top of marked.esm.js is preserved; see also node_modules/marked/LICENSE.md.
Why vendored: bundled plugins load in the browser as standalone ES modules and cannot resolve bare package specifiers. The plugin therefore ships the exact marked build the repo already depends on, rather than hand-rolling a markdown subset or adding a markdown helper to the plugin API.
Local modification: the trailing //# sourceMappingURL=marked.esm.js.map comment was removed because the (much larger) source map is not vendored. Everything else is byte-identical to the published file.
marked.esm.d.ts is a hand-written minimal declaration covering only the surface markdownDocument.ts uses. The plugin build (scripts/build-plugins.mjs) skips .d.ts files and copies .js assets verbatim, so the vendored module ships as-is.

Updating: after a marked upgrade in the root package.json, copy the new node_modules/marked/lib/marked.esm.js here, re-apply the sourceMappingURL removal, and update this note.
