In-Depth Engineering Explanation

If a theme loads a raw 4000x4000px image inside a 300x300px mobile thumbnail container, the mobile browser still downloads the entire multi-megabyte file. We audit Liquid image tags across your theme to ensure dynamic responsive sizing via the `image_url` filter with exact width parameters.
