/* =========================================================================
   Empire Tools — Shared component layer (chrome)
   -------------------------------------------------------------------------
   Canonical implementation of the UI every tool has in common: app shell,
   topbar, brand lockup, form controls, buttons, focus rings, status and
   empty/error states. Built entirely on the tokens in tokens.css.

   Import order in each app (main.tsx):
     import "@empire/design-system/tokens.css";   // variables
     import "./index.css";                          // per-app globals
     import App from "./App";                        // per-app App.css
     import "@empire/design-system/base.css";       // LAST = authoritative

   base.css is imported LAST on purpose: it governs the shared chrome so every
   app matches, even if an app still carries an older copy of a rule. Keep
   app-specific layout/components in the app's own CSS.

   No default rule here on purpose: every app defines its own complete

   selector risks the build's CSS minifier merging the two by plain
   property overwrite — whichever file lands later in that app's specific
