  The palette comes from @freecodecamp/ui. Its base.css defines the raw color
  variables (--gray90, --yellow45, ...) on :root and the semantic ones
  (--foreground-primary, --background-secondary, ...) on .light-palette /
  .dark-palette. The `extend` block below mirrors the library's own Tailwind
  config (https://github.com/freeCodeCamp/ui/blob/main/tailwind.config.js)
  so Classroom's utility classes use the same names as freeCodeCamp.
