Core JS Polyfill
Opt-in Core.js (v3.50.0) polyfills for older browsers. Not selected by default and not required for Next.js 16 on current browsers. profile=minimal emits only import 'core-js/stable'; profile=complete also emits per-feature side-effect imports. Tree shaking cannot remove those imports.
