/* Organize: the page's stylesheet. Mobile-first: the base rules are the PHONE layout; media queries add the
   tablet (700px+) and desktop (1100px+) layouts.

   COLOURS: never write a colour directly in a rule. Every colour is a variable defined in `:root` (light
   theme) and overridden in `:root[data-theme="dark"]` (dark theme, black background). The page is light
   unless the user picked dark (theme.js sets data-theme before the first paint).
