You need to read JavaScript-rendered content that curl/wget will not see. A user reports a UI bug and you need to reproduce it interactively to capture console errors, network requests, or layout state. You need to walk through a short flow (load page, click, observe) to verify acceptance criteria. The page is reachable as static HTML. Use curl/HTTP fetch — it is cheaper, faster, and more reliable.
