A pixel-perfect iOS e-commerce product detail screen shown in an iPhone 15 device frame, light mode. The top 45% of the screen is a full-bleed product image carousel showing a minimalist leather tote bag in cognac brown against a warm white background; carousel dots (5 total, second active) sit at the bottom of the image. Below the carousel: product name "Quill Leather Tote" in 22px semibold, a five-star rating row showing 4.7 stars and "(312 reviews)" in small gray text, and a price of "$148" in 20px bold with original price "$195" struck through in muted gray. A horizontal scrollable row shows colour swatches: cognac (selected, with border), black, forest green, stone. A text block in 14px regular describes the bag: two short lines of copy ending in a "Read more" link. At the bottom, a sticky button row: a heart icon button on the left and a full-width "Add to Bag" button in deep forest green. Tab bar: Shop, Search, Bag (with badge "2"), Profile.
