描述
Strict frontend design guardrails for building modern, minimal-visual-noise, airy, non-generic app UIs. Use whenever creating or changing frontend UI, React components, shadcn/ui themes, Tailwind styles, app layouts, or first-version product screens. This skill complements vertical/domain skills like CPQ, CRM, and similar app builders: follow the selected domain skill's workflow and layout requirements, then enforce this skill's shared visual rules for brand-aware theming, generous spacing, typography, contrast, roundedness, shadows, surface hierarchy, cardless defaults, no-sidebar defaults, and anti-pattern avoidance.
