Most appropriate block: Use a CodeProject. This work spans a server endpoint and a client UI, and in v0 the best-practice way to deliver deployable, testable code is a single CodeProject grouping a Next.js App Router page plus a route handler. If only documenting, plain text is fine; but for any code delivery or refactor (especially replacing Taiko with a server-friendly fetch/scraper or adapting to route handlers), a CodeProject is the correct container.

This version removes Taiko and top-level await, uses Puppeteer with Render-friendly flags, and splits the UI into public/index.html served by Express. To deploy on Render, create a Node Web Service, let it auto-detect the app, and ensure the Start Command is npm start. If Chromium issues arise, Render will typically work with Puppeteer’s bundled Chromium; otherwise set PUPPETEER_EXECUTABLE_PATH via environment variables if you provide a custom binary.
