   The most basic, page-wide rules: the CSS "reset", default body/heading/
   paragraph styling, the .container that centers page content, and the
   skip-link for keyboard users. Edit this file for anything that applies
   to EVERY page (fonts, base text color, page width).

   Needs variables.css loaded first (it uses var(--color-...) everywhere).
