VibeAxis (Fake Fast Detector / Tools)
Fake Fast Detector flags UX patterns that simulate performance—skeleton screens that never resolve, offscreen swaps, blocked interactions, hidden paywalls, and janky lazy-loading. Point it at a URL and get a plain-English report: issues, severity, reproduction steps, and a “fake-fast” score you can track across releases. It pairs with Lighthouse/WebPageTest: Lighthouse proves lab metrics; Fake Fast proves what humans feel.
