   ------------------------------------------------------------------
   Hand-written component classes.

   IMPORTANT: this project uses the Tailwind CDN build
   (cdn.tailwindcss.com), which only scans the HTML DOM for utility
   classes and injects matching styles on the fly — it does NOT
   process @apply directives in external stylesheets (that requires
   a PostCSS build step this project intentionally doesn't have).
   So every class below is written as plain, explicit CSS that
   mirrors the intended Tailwind utilities, rather than using
   @apply, which would silently do nothing under the CDN build.
