/* ==========================================================================
   Operations Tools — design-system component layer for the landing and login pages.

   Built on the Epos Now Design System (claude.ai/design project "Epos Now Design
   System", derived from @eposnow/ui-core). The token files beside this one are
   verbatim copies of that project: change them there and copy them over, never
   here. This file is our CSS version of its React primitives (SideNav, TopBar,
   MainHeader, Card, Button, Badge, Banner, AlertMessage), since this app has no
   React and no build step. It uses tokens only, no raw colours.

   The class names match public/portal/merchant-locator.css, which carries the same
   look for the map, so a page reads the same whichever stylesheet it links.
   Link ds/styles.css before this file.
