 * website/content/**\/*.md and the embedded chrome those files carry --
 * verified against website/templates/homepage.html, website/templates/
 * docs.html, and the built website/dist/**\/*.html output. No class names
 * are guessed: plain elements (h1-h4, p, ul/ol, code, pre, a, blockquote)
 * plus the real .docs-* / .skip-link classes and #hero/#problem/etc.
 * section ids used by the homepage and docs pages.
