Breakpoints class

Globally configurable device-class breakpoints, in logical pixels.

Configure once at startup, before runApp — e.g. in main():

void main() {
  Breakpoints.tablet = 700;
  Breakpoints.desktop = 1200;
  runApp(const ResponsiveScope(child: MyApp()));
}

These are process-global mutable statics; there is no per-call configuration. Set tablet < desktop: classify assumes ascending thresholds, so an inverted pair (e.g. tablet = 2000, desktop = 1024) silently misclassifies. There is no runtime guard for this, by minimalism — a misconfiguration is a startup error that is immediately visible in development.
