  styles.css  —  all styling for the site.
  Design tokens (colors, spacing) live in :root at the top, so you can
  re-skin the whole site by changing a handful of values here.

  primary surface; a warm off-white is the secondary. Sharp corners everywhere,
  text links instead of buttons, large editorial type.
