Validate the site's markup, CSS, and accessibility.

check (X)HTML5 and CSS validity on every markup file (inc. HTML, XHTML,
SVG). (xmllint is only relevant if you're using XML syntax).

Lints source CSS files with stylelint.

Uses both axe-core and the IBM Equal Access Checker to test
accessibility on every page in the sitemap.
