/* The Drone App — one stylesheet for the whole site.
   No build step, no JavaScript, no inline styles: the CSP is
   `script-src 'none'; style-src 'self'; default-src 'self'`.

   THE DESIGN. A saturated brand-blue field runs the full height of the page.
   Everything else is a large rounded card floating on it — paper, charcoal or
   blue. Between the cards the field shows through, carrying oversized outlined
   country names that run off the edge. Feature cards use a folder-tab shape.
   Both colour schemes keep the blue field; only its depth and the card
   treatments change, so the composition reads the same in either.

   Type is Outfit, a geometric sans, served from our own origin as one variable
   file (300-700). Zone colours are the app's own and are semantic: green means
   "you may fly here" and never appears on a control.
