/**
 * ext-content-mdx: ContentProcessor implementation backed by MDX + remark/rehype.
 *
 * Provides the `ContentProcessor` contract:
 *  - `compileMdx(options)` runs @mdx-js/mdx through Veryfront's remark +
 *    rehype plugin stack and returns compiled ESM plus extracted headings
 *    and frontmatter.
 *  - `compileMarkdown(options)` runs a unified markdown pipeline
 *    (remark-parse to remark-rehype to rehype-sanitize to rehype-stringify)
 *    producing sanitized HTML wrapped in a React component.
 *
 * Core's `src/transforms/md/compiler` and `src/transforms/mdx/compiler`
 * resolve this contract at call time. When the extension is not installed,
 * core throws an actionable install message (see
 * `src/extensions/recommendations.ts`).
 *
 * @module extensions/ext-content-mdx
