   app.css — the Robotack OS shell and its shared components.
   Loads after base-tokens.css on every signed-in page.

   Prefix: os- (shell + shared components). Pages add their own
   <page>.css with their own prefix. Bootstrap is present on DataTable
   pages, so nothing here reuses a Bootstrap class name (.modal,
   .dropdown-menu, .nav, .badge...).
   Tokens only; dark mode = html.dark token overrides; RTL via logical
   properties. One motion budget: things move when you act on them.
