A product design and front-end review council for interfaces, design systems, visual direction and UI implementation. A Principal Product Designer judges flow, hierarchy, typography, color and motion; a Staff Frontend Engineer checks semantic HTML, component states, Core Web Vitals and build cost; an Accessibility Specialist checks WCAG 2.2 AA conformance; a UX Research lead tests the claims against user evidence; and a Devil's Advocate challenges the consensus. The designers and engineers cite the council's on-server design and web-standards reference library and compute contrast instead of eyeballing it. Ideal for design critiques, redesign decisions, palette and type choices, and pre-launch UI reviews. ~2-3 minutes.
