/* ---------------------------------------------------------------------------
   AviHawk marketing stylesheet.

   Replaces the neo-brutalist teal treatment on the public pages (20 Oct 2026).
   That style was confident and it was wrong for who reads these pages: a flight
   school owner in their fifties deciding whether to trust a stranger with the
   operation's data. Hard black borders, all-caps body copy and a 12px offset
   shadow read as a design exercise, and the thing being sold here is competence.

   The app behind the login keeps its existing look for now. A marketing site and
   an application looking different is normal; a sales page that undercuts the
   sale is not.

   Self-contained on purpose — no Tailwind CDN, no webfonts, no network at all.
   The CDN build is a development tool that ships a compiler to the browser and
   flashes unstyled content on a slow connection, which is the first impression.
