Guides UI software engineering—implementing screens and components from design specs, design tokens,
responsive layout, interaction states, forms, and API-boundary loading/error UI in React/Next.js or
similar stacks. Covers component library usage, basic WCAG implementation, and visual QA—not for
senior front-end architecture or Core Web Vitals programs (senior-frontend-software-engineer),
web auth/CORS/session security (web-application-developer), UX discovery without code
(product-designer), interaction specs and coded prototypes (ux-software-engineer), or backend
APIs and schemas (fullstack-software-engineer).
