# Performance UX Measure representative real journeys and devices. Inspect LCP, INP, CLS, loading waterfalls, client/server boundaries, hydration, bundle/dependency weight, fonts, images, animation cost, long tasks, and large lists. Relate every finding to perceived experience: delayed meaning, blocked input, layout instability, missing feedback, or battery/network cost. Recommend the highest-impact fix and preserve visual/interaction intent. Beautiful but sluggish is not excellent design.
