Single-direction interface design, design-contract authoring, implementation states, accessibility, and rendered visual verification.
Establish one implementation-ready interface direction with content hierarchy, typography, spacing, color, component geometry, responsive behavior, states, accessibility, and performance constraints. Use before creating or substantially redesigning a web or product interface. Do not generate unsolicited variants or replace an existing design system without an explicit redesign request.
Verify a rendered interface against its accepted design direction across representative viewports, states, keyboard use, accessibility, content density, and runtime behavior. Use after UI implementation or when diagnosing visual regressions. Do not approve a design from source code alone when a rendered surface can be inspected or redesign during visual QA.
