  // - `app/providers/DappBrowserProvider.tsx` — Capacitor inappbrowser
  //   provider wired to native plugins, exercised via mobile-e2e.
  // - `components/TransactionProgressModal.tsx` — react-modal portal
  //   with framer-motion animation, covered by Playwright.
  // - `app/icons/v2/index.tsx` — barrel file of SVG re-exports.
  // - `lib/mobile/faucet-webview.ts` — Capacitor InAppBrowser wrapper.
  // - `packages/dapp-browser/` — external package build output.
