My online store is already live and generating traffic, but a few lingering code quirks are keeping it from being truly production-ready. The trouble spots are clear: the checkout process sometimes stalls, product pages occasionally mis-render, and new users report hiccups during sign-up and login. The site runs on standard HTML/CSS with JavaScript calls to a REST-style API, so I suspect a mix of front-end markup issues and wiring errors between the browser and our endpoints. In particular, the product display is suffering from images that refuse to load, inaccurate details being pulled through the API, and layout shifts that break the responsive grid. Your task is to trace and eliminate these bugs so that: • Every shopper can move from cart to confirmed order without an error banner or silent failure. • Product cards and detail pages show the correct data, images appear first time, quick view, compare, and the design stays intact on desktop and mobile. • Sign-up and login complete smoothly, with session tokens handled correctly and no console warnings. Once you’ve patched the code, I’ll run a final QA pass; as long as those three flows work flawlessly in Chrome, Safari and Firefox, we’re done. Please push your fixes via Git so I can review the commits before we merge to the main branch.
