/* SEO-03: the only asset these pages load. Its URL carries a hash of these
   bytes, so it is served immutable for a year and still changes the instant
   this file does.

   Tokens are the app's (frontend/src/app.css) so the two renderings of one
   screen look like the same site. Tailwind is not involved — pulling the SPA's
   generated stylesheet in here would ship a few hundred KB of utilities to
   every crawler for the sake of a dozen rules. */
