   This stylesheet is a drop-in replacement for the inline <style>
   block that previously lived in templates/ui/base.html.

   It is BACKWARDS-COMPATIBLE: every legacy class name from the old
   base.html (`.card`, `.badge-ok`, `.badge-warn`, `.badge-fail`,
   `.btn-primary`, `.btn-ghost`, `.btn-danger`, `.ni`, `.ni.active`)
   is still defined here and visually upgraded. Pages built before
   the migration keep working until you have time to replace their
   inline styles with the new semantic classes.
