In-Depth Engineering Explanation

In vintage architecture, only index.liquid supported drag-and-drop sections, forcing merchants to hard-code product, collection, and blog pages. With Storefront 2.0, every template uses a .json file defining sections and blocks dynamically. Furthermore, app blocks allow clean installation and uninstallation of apps without leaving behind ghost JavaScript in your theme.liquid.
