Build a Chrome extension called "Cross-Site Wishlist" that adds a heart icon to product pages on any e-commerce site. Click to save the product (title, price, image, URL) parsed from OpenGraph + structured-data + heuristic selectors into chrome.storage.local. A full-page wishlist view shows all saved products grouped by site, with current-vs-saved price diffs (re-fetched via the service worker) and remove buttons. Permissions: storage, activeTab. Host permissions: <all_urls>. Manifest V3.
