Performance articles and design guides

A gorgeous interface that takes four seconds to paint is a broken interface. Performance is where design meets the network, and these articles keep both in frame. We get into Core Web Vitals, image formats, font loading strategy, layout shift, and the animation choices that quietly tank a frame rate. Aiming for LCP under 2.5 seconds is a design constraint, not just an engineering one. Written for designers and developers who refuse to trade speed for polish. Concrete measurements, before-and-after numbers, and the tradeoffs nobody warns you about.
