Build or restyle frontends using App Shell UI — a clean, restrained macOS-style desktop-tool shell (left nav + content, soft surfaces, raised cards, single brand accent, settings-list language) with first-class light and dark themes. Use when the user asks for app-shell-ui, /app-shell-ui, 桌面工具风 UI, 系统设置感界面, 应用外壳, sidebar shell, Clash/设置风格前端, light/dark desktop client UI, 深色主题, 浅色主题, theme toggle, or wants pages that share one reusable app chrome across chat / settings / console / mail-like layouts. Also use for high-fidelity HTML/React demos from tokens and component recipes.
