## From README

Frontend UI Engineering Overview Build production-quality user interfaces that are accessible, performant, and visually polished. The goal is UI that looks like it was built by a design-aware engineer at a top company — not like it was generated by an AI. This means real design system adherence, proper accessibility, thoughtful interaction patterns, and no generic "AI aesthetic." When to Use Building new UI components or pages Modifying existing user-facing interfaces Implementing responsive layouts Adding interactivity or state management Fixing visual or UX issues Component Architecture File Structure Colocate everything related to a component: Component Patterns Prefer composition over configuration: Keep components focused: Separate data fetching from presentation: State Management Choose the simplest approach that works: Avoid prop drilling deeper than 3 levels. If you're passing props through components that don't use them, introduce context or restructure the component tree.
