   Organised in three parts:
   1. Design tokens (custom properties) — every color, font and radius
      used anywhere on the page is defined once here. Change a value in
      this block and it updates everywhere it's used.
   2. Base/reset — sensible defaults for raw HTML elements.
   3. Components — one section per part of the page, top to bottom,
      in the same order they appear in index.html.
