  .bg-base is defined here as a plain CSS class rather than a Tailwind custom
  color. Previously `base` was in the Tailwind colors config, which caused
  Tailwind CDN to generate a `.text-base { color: #f3f4f6 }` rule that clashed
  with the built-in `.text-base` font-size utility and silently overrode
  `text-gray-900` (and similar) on any element that also had `text-base` for
  its font size. Moving the definition here removes the collision entirely.
