/* themeerkatz.com. Hand written, because the app's Tailwind is a 254 KB script that compiles classes in the
   browser - acceptable behind a login, not for the first page a stranger sees.

   The colour tokens are copied from gui/static/app.css rather than shared, since the two are deployed
   separately and a marketing page that broke because the app's stylesheet moved would be a silly way to lose a
   front door. Copied, not imported: if the palette changes there, change it here too. Light and dark are
   separately stepped, not an automatic flip. */
