/* Shared visual base for every entry point of the zone (terminal, cabinet,
   and the second pillar later). Served from /shared/base.css, linked BEFORE
   the application stylesheet so an application rule always wins on a tie.

   What lives here: the donor-native palette, the reset, the base typography,
   the top-bar frame, and the look of the sign-in card. What deliberately does
   NOT: where #login-overlay sits. The terminal covers only its chart area
   (the navigation stays visible behind it), the cabinet covers the page --
   that is each application's business, and pretending otherwise would have
   changed the accepted look of the terminal's sign-in screen. */
