/* ==========================================================================
   apps.css
   Shared styling for the apps section. Dark, editorial, image-forward.
   Derived from the ai-examples look: #111 ground, blue-gray panels,
   big tight headlines, muted grey body copy, pill links and tech tags.

   Each app page sets its own --accent (snitscanner cobalt, ExpressionGate
   oxide orange) so the pages feel like the products they describe.
