I need a small but precise Liquid (and, if needed, JavaScript) tweak applied to the product-page template of my live Shopify store. The goal is to insert custom code that extends the page’s current capabilities while keeping everything else—theme styling, app integrations, and load speed—fully intact. Scope • Work only inside the product-page template; the homepage and checkout are already fine. • Code must sit cleanly in its own snippet or Section so future theme updates remain straightforward. • Result should display and function identically across modern desktop and mobile browsers. Deliverable A commented Liquid/JS snippet plus clear placement instructions so I can replicate or roll back the change if needed. Once installed, the product pages should render exactly as intended with no console errors or layout shifts. I can provide theme access, preview links, and any design files you need right away. Let me know your estimated turnaround and any questions about the store’s current setup, and we can get started.
