Build a Chrome extension called "Review Trust Score" that, on Amazon and similar listings, scrapes visible reviews and computes a fake-review heuristic score: ratio of 5-star to 1-star, reviewer history sparsity (single-review profiles), repeated phrases across reviews, burst patterns (many reviews same week), and generic-language signals. Inject a badge near the star rating with the score (0-100) and a click-to-expand breakdown. Permissions: storage, activeTab. Host permissions: https://www.amazon.com/*, https://www.amazon.co.uk/*. Manifest V3 with content script.
