Agent Skills: ui-design

UI design and component-system collapse hub for Epicenter interfaces. Use when designing, implementing, polishing, redesigning, or reviewing visible UI; choosing @epicenter/ui components; changing packages/ui; building Svelte state surfaces; or replacing class-heavy markup, arbitrary Tailwind values, custom colors, and local interface primitives. Every meaningful UI change preserves the user-visible objective while challenging inherited structure and collapsing toward shared primitives. Not for a tiny CSS-only repair unless it reveals a broader pattern.
