ui-ux-guide

Run a structured UI/UX consultation to either (a) co-design a project-specific design system and emit `design-spec.md`, (b) review an existing UI with prioritized fixes, or (c) emit compact do/don't rules for a surface. Triggers when the user wants to define / build / refine a design system or design tokens, asks for a design spec, asks for a full UI review of a screen / mockup / PR, or wants design rules for a surface type. Do NOT trigger for narrow one-off questions ("is this color OK?", "should this button be larger?") — answer those directly without invoking the consultation flow.
