(!) Some chunks are larger than 500 KiB after minification. Consider:
- Using dynamic import() to code-split the application
- Use build.rollupOptions.output.manualChunks to improve chunking: https://rollupjs.org/guide/en/#outputmanualchunks
- Adjust chunk size limit for this warning via build.chunkSizeWarningLimit.
