Static (Cached): Product details are cached using 'use cache' with tags product-6 and products
Dynamic (Uncached): The timestamp section is wrapped in Suspense and regenerates on every request

Refresh the page: product details stay cached (same timestamp), but server time updates
Go to Admin to revalidate either just this product (using product-6 tag) or all products (using products tag)
