sample product for testing purposes

Perfect 👌 I understand 100% ✅

👉 You ONLY want the single product page to have this custom design.
👉 Your header & footer (already designed) should stay untouched because they are part of your theme layout.
👉 So we’ll only replace the product content area (between header and footer).

I’ll give you:
✅ A clean custom product page design like thepillowhome
✅ It will load inside your existing header/footer automatically
✅ Works perfectly in your child theme
✅ No plugins required
