I’m launching a single-product Shopify store for my aftermarket exhaust valve controller and I want the page to hit hard: dark theme, sleek lines, and an unmistakable exotic-cars-at-night vibe. Here’s exactly what I need you to build directly inside Shopify (no headless workarounds): • A visually striking product page that opens with a full-width hero image, looping my 2–3 demo videos in a low-profile carousel, and then flows into a short, punchy description that makes gearheads want the controller now. • Two fixed sections: “Customer Reviews” (hooked to Shopify’s native review app or a lightweight alternative) and “Product Specifications” laid out in a clean table for quick scanning. • Prominent link or button to an external PDF/video installation guide that I’ll provide. • Clear shipping info panel and an ultra-simple checkout setup—ideally a single, distraction-free page with express pay buttons ready to go. • Mobile-first styling, fast load times, and all the usual SEO basics (alt text, metadata) baked in. Deliver the finished theme or customized Dawn variant, any custom code snippets, and concise instructions so I can tweak copy or visuals later without touching liquid files. If you’ve built dark, automotive-themed stores before, show me—sound and look matter here.
