// --- React 19 act() fix (DEBE ir primero, antes que @testing-library) ---
//
// React 19 + Vitest 4 + Vite: @vitejs/plugin-react añade "react-server" a
// resolve conditions. react-dom/test-utils (CJS) require("react") internamente
// y resuelve a react-server (sin act). Esto rompe @testing-library/react.
//
// El fix real está en vitest.config.ts (plugin force-react-browser-build +
// conditions browser + deps inline). Si sigue fallando, cada test file
// debe añadir un vi.mock al inicio. Ver comment en vitest.config.ts.

// funcionen igual que en el navegador.
