Design Philosophy & Best Practices

设计理念与最佳实践

ALWAYS follow these principles:
  1. Mobile-First Responsive Design:
    • Start with mobile layouts (
      sm:
      , 
      md:
      , 
      lg:
      , 
      xl:
      , 
      2xl:
      )
    • Use fluid spacing and typography
    • Test on multiple screen sizes
    • Avoid fixed widths, use responsive units
  2. Accessibility First (WCAG 2.1 AA):
    • Semantic HTML structure (
      <nav>
      , 
      <main>
      , 
      <article>
      )
    • Proper ARIA attributes when needed
    • Keyboard navigation support
    • Focus states for interactive elements
    • Sufficient color contrast (4.5:1 minimum)
    • Screen reader friendly labels
  3. Consistent Design System:
    • Use Tailwind design tokens consistently
    • Establish spacing scale (4px base unit)
    • Define typography hierarchy
    • Create reusable component variants
    • Maintain consistent color palette
  4. Performance Optimization:
    • Use 
      cn()
      utility for conditional classes
    • Avoid inline styles when possible
    • Optimize images with lazy loading and native 
      <img loading="lazy" />
    • Code split heavy components with React.lazy()
    • Minimize CSS bundle size
  5. Component Architecture:
    • Single Responsibility Principle
    • Compose small, focused components
    • Extract reusable patterns
    • Use TypeScript for props
    • All components are client-side (Vite + React)
    • Use React.lazy() for code splitting when needed
请始终遵循以下原则：
  1. 移动端优先的响应式设计：
    • 从移动端布局开始（
      sm:
      、
      md:
      、
      lg:
      、
      xl:
      、
      2xl:
      ）
    • 使用流式间距和排版
    • 在多尺寸屏幕上测试
    • 避免固定宽度，使用响应式单位
  2. 可访问性优先（WCAG 2.1 AA）：
    • 使用语义化HTML结构（
      <nav>
      、
      <main>
      、
      <article>
      ）
    • 必要时添加正确的ARIA属性
    • 支持键盘导航
    • 为交互元素添加焦点状态
    • 确保足够的色彩对比度（文本最小4.5:1）
    • 支持屏幕阅读器的标签
  3. 一致的设计系统：
    • 统一使用Tailwind设计令牌
    • 建立间距规范（4px为基础单位）
    • 定义排版层级
    • 创建可复用的组件变体
    • 保持一致的调色板
  4. 性能优化：
    • 使用
      cn()
      工具类处理条件样式
    • 尽可能避免内联样式
    • 通过懒加载和原生
      <img loading="lazy" />
      优化图片
    • 使用React.lazy()对大型组件进行代码分割
    • 最小化CSS包体积
  5. 组件架构：
    • 单一职责原则
    • 组合小型、聚焦的组件
    • 提取可复用模式
    • 使用TypeScript定义Props
    • 所有组件均为客户端组件（Vite + React）
    • 按需使用React.lazy()进行代码分割

shadcn/ui Component Patterns (MANDATORY)

shadcn/ui组件模式（强制要求）

Standard component structure:
typescript
import { cn } from "@/lib/utils";
import { Button } from "@/components/ui/button";
import {
  Card,
  CardContent,
  CardDescription,
  CardHeader,
  CardTitle,
} from "@/components/ui/card";

interface MyComponentProps {
  title: string;
  description?: string;
  variant?: "default" | "destructive" | "outline";
  className?: string;
}

export function MyComponent({
  title,
  description,
  variant = "default",
  className,
}: MyComponentProps) {
  return (
    <Card className={cn("w-full max-w-md", className)}>
      <CardHeader>
        <CardTitle>{title}</CardTitle>
        {description && <CardDescription>{description}</CardDescription>}
      </CardHeader>
      <CardContent>
        <Button variant={variant}>Click me</Button>
      </CardContent>
    </Card>
  );
}
标准组件结构：
typescript
import { cn } from "@/lib/utils";
import { Button } from "@/components/ui/button";
import {
  Card,
  CardContent,
  CardDescription,
  CardHeader,
  CardTitle,
} from "@/components/ui/card";

interface MyComponentProps {
  title: string;
  description?: string;
  variant?: "default" | "destructive" | "outline";
  className?: string;
}

export function MyComponent({
  title,
  description,
  variant = "default",
  className,
}: MyComponentProps) {
  return (
    <Card className={cn("w-full max-w-md", className)}>
      <CardHeader>
        <CardTitle>{title}</CardTitle>
        {description && <CardDescription>{description}</CardDescription>}
      </CardHeader>
      <CardContent>
        <Button variant={variant}>Click me</Button>
      </CardContent>
    </Card>
  );
}

Tailwind CSS Patterns

Responsive Layout Example

响应式布局示例

typescript
<div className="grid grid-cols-1 gap-4 sm:grid-cols-2 lg:grid-cols-3 xl:grid-cols-4">
  {items.map((item) => (
    <Card key={item.id} className="flex flex-col">
      <CardHeader>
        <CardTitle className="text-lg">{item.title}</CardTitle>
      </CardHeader>
      <CardContent className="flex-1">
        <p className="text-sm text-muted-foreground">{item.description}</p>
      </CardContent>
    </Card>
  ))}
</div>
typescript
<div className="grid grid-cols-1 gap-4 sm:grid-cols-2 lg:grid-cols-3 xl:grid-cols-4">
  {items.map((item) => (
    <Card key={item.id} className="flex flex-col">
      <CardHeader>
        <CardTitle className="text-lg">{item.title}</CardTitle>
      </CardHeader>
      <CardContent className="flex-1">
        <p className="text-sm text-muted-foreground">{item.description}</p>
      </CardContent>
    </Card>
  ))}
</div>

Dark Mode Support

深色模式支持

typescript
<div className="bg-white dark:bg-slate-950">
  <h1 className="text-slate-900 dark:text-slate-50">Heading</h1>
  <p className="text-slate-600 dark:text-slate-400">Description</p>
</div>
typescript
<div className="bg-white dark:bg-slate-950">
  <h1 className="text-slate-900 dark:text-slate-50">Heading</h1>
  <p className="text-slate-600 dark:text-slate-400">Description</p>
</div>

Custom Component with Variants

带变体的自定义组件

typescript
import { cva, type VariantProps } from "class-variance-authority";

const alertVariants = cva("rounded-lg border p-4", {
  variants: {
    variant: {
      default: "bg-background text-foreground",
      destructive:
        "border-destructive/50 text-destructive dark:border-destructive",
      success:
        "border-green-500/50 bg-green-50 text-green-900 dark:bg-green-950 dark:text-green-50",
    },
  },
  defaultVariants: {
    variant: "default",
  },
});

interface AlertProps extends VariantProps<typeof alertVariants> {
  children: React.ReactNode;
  className?: string;
}

export function Alert({ variant, className, children }: AlertProps) {
  return (
    <div className={cn(alertVariants({ variant }), className)}>{children}</div>
  );
}
typescript
import { cva, type VariantProps } from "class-variance-authority";

const alertVariants = cva("rounded-lg border p-4", {
  variants: {
    variant: {
      default: "bg-background text-foreground",
      destructive:
        "border-destructive/50 text-destructive dark:border-destructive",
      success:
        "border-green-500/50 bg-green-50 text-green-900 dark:bg-green-950 dark:text-green-50",
    },
  },
  defaultVariants: {
    variant: "default",
  },
});

interface AlertProps extends VariantProps<typeof alertVariants> {
  children: React.ReactNode;
  className?: string;
}

export function Alert({ variant, className, children }: AlertProps) {
  return (
    <div className={cn(alertVariants({ variant }), className)}>{children}</div>
  );
}

"use client";

import { motion } from "framer-motion";

export function FadeIn({ children }: { children: React.ReactNode }) {
  return (
    <motion.div
      initial={{ opacity: 0, y: 20 }}
      animate={{ opacity: 1, y: 0 }}
      transition={{ duration: 0.3 }}
    >
      {children}
    </motion.div>
  );
}
typescript
"use client";

import { motion } from "framer-motion";

export function FadeIn({ children }: { children: React.ReactNode }) {
  return (
    <motion.div

});

export function ProfileForm() {
  const form = useForm({
    defaultValues: {
      username: "",
      email: "",
    },
    validators: {
      onChange: profileSchema,
    },
    onSubmit: async ({ value }) => {
      console.log("Form submitted:", value);
    },
  });

Design Tokens & Dark Mode (MANDATORY)

设计令牌与深色模式（强制要求）

IMPORTANT: For Gesttione-specific projects, use the 
gesttione-design-system
skill which provides complete brand color tokens, metric color semantics, and company-specific design patterns.
重要提示：针对Gesttione特定项目，请使用
gesttione-design-system
技能，该技能提供完整的品牌色彩令牌、指标色彩语义及公司特定设计模式。

Color Token System

色彩令牌系统

ALWAYS use CSS custom properties (design tokens) for colors to ensure proper dark mode support:
css
/* app.css or globals.css */
@import "tailwindcss";

:root {

Using Design Tokens in Components

在组件中使用设计令牌

ALWAYS use semantic token names, NOT hardcoded colors:
typescript
// ✅ Good - Uses design tokens
<div className="bg-background text-foreground">
  <Card className="bg-card text-card-foreground">
    <h2 className="text-primary">Heading</h2>
    <p className="text-muted-foreground">Description</p>
    <Button className="bg-primary text-primary-foreground">Action</Button>
  </Card>
</div>

// ❌ Bad - Hardcoded colors break dark mode
<div className="bg-white text-black">
  <div className="bg-gray-100 text-gray-900">
    <h2 className="text-blue-600">Heading</h2>
    <p className="text-gray-500">Description</p>
    <button className="bg-blue-600 text-white">Action</button>
  </div>
</div>
请始终使用语义化令牌名称，而非硬编码色彩：
typescript
// ✅ 推荐 - 使用设计令牌
<div className="bg-background text-foreground">
  <Card className="bg-card text-card-foreground">
    <h2 className="text-primary">Heading</h2>
    <p className="text-muted-foreground">Description</p>
    <Button className="bg-primary text-primary-foreground">Action</Button>
  </Card>
</div>

// ❌ 不推荐 - 硬编码色彩会破坏深色模式
<div className="bg-white text-black">
  <div className="bg-gray-100 text-gray-900">
    <h2 className="text-blue-600">Heading</h2>
    <p className="text-gray-500">Description</p>
    <button className="bg-blue-600 text-white">Action</button>
  </div>
</div>

Brand Color Scales

品牌色彩层级

Create accessible color scales for brand colors:
css
:root {
  /* Brand primary color */
  --brand-primary: #428deb;

  /* Brand primary scale for accessibility */
  --brand-primary-50: #eff6ff; /* Very light */
  --brand-primary-100: #dbeafe; /* Light */
  --brand-primary-200: #bfdbfe;
  --brand-primary-300: #93c5fd;
  --brand-primary-400: #60a5fa;
  --brand-primary-500: var(--brand-primary); /* Base */
  --brand-primary-600: #2563eb; /* AA compliant on white */
  --brand-primary-700: #1d4ed8; /* AAA compliant on white */
  --brand-primary-800: #1e40af;
  --brand-primary-900: #1e3a8a; /* Darkest */
}

@theme inline {
  --color-brand-primary-50: var(--brand-primary-50);
  --color-brand-primary-100: var(--brand-primary-100);
  --color-brand-primary-200: var(--brand-primary-200);
  --color-brand-primary-300: var(--brand-primary-300);
  --color-brand-primary-400: var(--brand-primary-400);
  --color-brand-primary-500: var(--brand-primary-500);
  --color-brand-primary-600: var(--brand-primary-600);
  --color-brand-primary-700: var(--brand-primary-700);
  --color-brand-primary-800: var(--brand-primary-800);
  --color-brand-primary-900: var(--brand-primary-900);
}
typescript
// Using brand color scales
<div className="bg-brand-primary-50 dark:bg-brand-primary-900">
  <h2 className="text-brand-primary-700 dark:text-brand-primary-300">
    Accessible heading
  </h2>
  <Button className="bg-brand-primary-600 hover:bg-brand-primary-700">
    Action
  </Button>
</div>
为品牌色彩创建符合可访问性的层级：
css
:root {
  /* 品牌主色 */
  --brand-primary: #428deb;

  /* 品牌主色的可访问性层级 */
  --brand-primary-50: #eff6ff; /* 极浅 */
  --brand-primary-100: #dbeafe; /* 浅 */
  --brand-primary-200: #bfdbfe;
  --brand-primary-300: #93c5fd;
  --brand-primary-400: #60a5fa;
  --brand-primary-500: var(--brand-primary); /* 基础色 */
  --brand-primary-600: #2563eb; /* 在白色背景上符合AA标准 */
  --brand-primary-700: #1d4ed8; /* 在白色背景上符合AAA标准 */
  --brand-primary-800: #1e40af;
  --brand-primary-900: #1e3a8a; /* 最深色 */
}

@theme inline {
  --color-brand-primary-50: var(--brand-primary-50);
  --color-brand-primary-100: var(--brand-primary-100);
  --color-brand-primary-200: var(--brand-primary-200);
  --color-brand-primary-300: var(--brand-primary-300);
  --color-brand-primary-400: var(--brand-primary-400);
  --color-brand-primary-500: var(--brand-primary-500);
  --color-brand-primary-600: var(--brand-primary-600);
  --color-brand-primary-700: var(--brand-primary-700);
  --color-brand-primary-800: var(--brand-primary-800);
  --color-brand-primary-900: var(--brand-primary-900);
}
typescript
// 使用品牌色彩层级
<div className="bg-brand-primary-50 dark:bg-brand-primary-900">
  <h2 className="text-brand-primary-700 dark:text-brand-primary-300">
    可访问性标题
  </h2>
  <Button className="bg-brand-primary-600 hover:bg-brand-primary-700">
    操作按钮
  </Button>
</div>

Semantic Color Tokens

语义色彩令牌

Use semantic tokens for specific purposes:
NOTE: For Gesttione projects, use the complete metric color system defined in the 
gesttione-design-system
skill, which includes revenue, CMV, purchases, costs, customers, average ticket, and margin percentage with proper semantic naming.
css
:root {
  /* Example metric/dashboard colors (use gesttione-design-system for Gesttione projects) */
  --metric-revenue: #105186;
  --metric-cost: #ea580c;
  --metric-customers: #0ea5e9;
  --metric-success: #16a34a;
  --metric-warning: #f59e0b;
  --metric-danger: #dc2626;

  /* Surface colors (backgrounds) using color-mix */
  --metric-revenue-surface: color-mix(
    in srgb,
    var(--metric-revenue) 18%,
    transparent
  );
  --metric-cost-surface: color-mix(
    in srgb,
    var(--metric-cost) 18%,
    transparent
  );
  --metric-success-surface: color-mix(
    in srgb,
    var(--metric-success) 20%,
    transparent
  );
}

.dark {
  /* Adjust opacity for dark mode */
  --metric-revenue-surface: color-mix(
    in srgb,
    var(--metric-revenue) 28%,
    transparent
  );
  --metric-cost-surface: color-mix(
    in srgb,
    var(--metric-cost) 28%,
    transparent
  );
  --metric-success-surface: color-mix(
    in srgb,
    var(--metric-success) 32%,
    transparent
  );
}

@theme inline {
  --color-metric-revenue: var(--metric-revenue);
  --color-metric-revenue-surface: var(--metric-revenue-surface);
  --color-metric-cost: var(--metric-cost);
  --color-metric-cost-surface: var(--metric-cost-surface);
  --color-metric-success: var(--metric-success);
  --color-metric-success-surface: var(--metric-success-surface);
}
typescript
// Using semantic tokens for metrics
<Card className="bg-metric-revenue-surface border-metric-revenue/20">
  <div className="flex items-center gap-2">
    <div className="h-2 w-2 rounded-full bg-metric-revenue" />
    <span className="text-sm font-medium text-metric-revenue">Revenue</span>
  </div>
  <p className="text-2xl font-bold">$125,430</p>
</Card>
针对特定场景使用语义化令牌：
注意：针对Gesttione项目，请使用
gesttione-design-system
技能中定义的完整指标色彩系统，包括收入、CMV、采购、成本、客户、客单价及利润率的语义化命名。
css
:root {
  /* 指标/仪表盘色彩示例（Gesttione项目请使用gesttione-design-system） */
  --metric-revenue: #105186;
  --metric-cost: #ea580c;
  --metric-customers: #0ea5e9;
  --metric-success: #16a34a;
  --metric-warning: #f59e0b;
  --metric-danger: #dc2626;

  /* 使用color-mix创建表面色（背景） */
  --metric-revenue-surface: color-mix(
    in srgb,
    var(--metric-revenue) 18%,
    transparent
  );
  --metric-cost-surface: color-mix(
    in srgb,
    var(--metric-cost) 18%,
    transparent
  );
  --metric-success-surface: color-mix(
    in srgb,
    var(--metric-success) 20%,
    transparent
  );
}

.dark {
  /* 调整深色模式下的透明度 */
  --metric-revenue-surface: color-mix(
    in srgb,
    var(--metric-revenue) 28%,
    transparent
  );
  --metric-cost-surface: color-mix(
    in srgb,
    var(--metric-cost) 28%,
    transparent
  );
  --metric-success-surface: color-mix(
    in srgb,
    var(--metric-success) 32%,
    transparent
  );
}

@theme inline {
  --color-metric-revenue: var(--metric-revenue);
  --color-metric-revenue-surface: var(--metric-revenue-surface);
  --color-metric-cost: var(--metric-cost);
  --color-metric-cost-surface: var(--metric-cost-surface);
  --color-metric-success: var(--metric-success);
  --color-metric-success-surface: var(--metric-success-surface);
}
typescript
// 使用语义化令牌展示指标
<Card className="bg-metric-revenue-surface border-metric-revenue/20">
  <div className="flex items-center gap-2">
    <div className="h-2 w-2 rounded-full bg-metric-revenue" />

Dark Mode Toggle

深色模式切换器

Implement dark mode toggle with React state and localStorage:
typescript
import { Moon, Sun } from "lucide-react";
import { useEffect, useState } from "react";
import { Button } from "@/shared/components/ui/button";

export function ThemeToggle() {
  const [theme, setTheme] = useState<"light" | "dark">("light");

  useEffect(() => {
    // Read theme from localStorage on mount
    const savedTheme = localStorage.getItem("theme") as "light" | "dark" | null;
    const prefersDark = window.matchMedia(
      "(prefers-color-scheme: dark)"
    ).matches;
    const initialTheme = savedTheme || (prefersDark ? "dark" : "light");

    setTheme(initialTheme);
    document.documentElement.classList.toggle("dark", initialTheme === "dark");
  }, []);

  const toggleTheme = () => {
    const newTheme = theme === "dark" ? "light" : "dark";
    setTheme(newTheme);
    localStorage.setItem("theme", newTheme);
    document.documentElement.classList.toggle("dark", newTheme === "dark");
  };

  return (
    <Button
      variant="ghost"
      size="icon"
      onClick={toggleTheme}
      aria-label="Toggle theme"
    >
      <Sun className="h-5 w-5 rotate-0 scale-100 transition-all dark:-rotate-90 dark:scale-0" />
      <Moon className="absolute h-5 w-5 rotate-90 scale-0 transition-all dark:rotate-0 dark:scale-100" />
      <span className="sr-only">Toggle theme</span>
    </Button>
  );
}
使用React状态和localStorage实现深色模式切换：
typescript
import { Moon, Sun } from "lucide-react";
import { useEffect, useState } from "react";
import { Button } from "@/shared/components/ui/button";

export function ThemeToggle() {
  const [theme, setTheme] = useState<"light" | "dark">("light");

  useEffect(() => {
    // 初始化时从localStorage读取主题
    const savedTheme = localStorage.getItem("theme") as "light" | "dark" | null;
    const prefersDark = window.matchMedia(
      "(prefers-color-scheme: dark)"
    ).matches;
    const initialTheme = savedTheme || (prefersDark ? "dark" : "light");

    setTheme(initialTheme);
    document.documentElement.classList.toggle("dark", initialTheme === "dark");
  }, []);

  const toggleTheme = () => {
    const newTheme = theme === "dark" ? "light" : "dark";
    setTheme(newTheme);
    localStorage.setItem("theme", newTheme);
    document.documentElement.classList.toggle("dark", newTheme === "dark");
  };

  return (
    <Button
      variant="ghost"
      size="icon"
      onClick={toggleTheme}
      aria-label="Toggle theme"
    >
      <Sun className="h-5 w-5 rotate-0 scale-100 transition-all dark:-rotate-90 dark:scale-0" />
      <Moon className="absolute h-5 w-5 rotate-90 scale-0 transition-all dark:rotate-0 dark:scale-100" />
      <span className="sr-only">切换主题</span>
    </Button>
  );
}

Theme Context Provider (Optional)

主题上下文提供者（可选）

For more advanced theme management, create a custom context:
typescript
// src/providers/theme-provider.tsx
import {
  createContext,
  useContext,
  useEffect,
  useState,
  type ReactNode,
} from "react";

type Theme = "light" | "dark" | "system";

interface ThemeContextType {
  theme: Theme;
  setTheme: (theme: Theme) => void;
  resolvedTheme: "light" | "dark";
}

const ThemeContext = createContext<ThemeContextType | undefined>(undefined);

export function ThemeProvider({ children }: { children: ReactNode }) {
  const [theme, setThemeState] = useState<Theme>("system");
  const [resolvedTheme, setResolvedTheme] = useState<"light" | "dark">("light");

  useEffect(() => {
    const savedTheme = (localStorage.getItem("theme") as Theme) || "system";
    setThemeState(savedTheme);
  }, []);

  useEffect(() => {
    const root = document.documentElement;
    const applyTheme = (newTheme: "light" | "dark") => {
      root.classList.remove("light", "dark");
      root.classList.add(newTheme);
      setResolvedTheme(newTheme);
    };

    if (theme === "system") {
      const prefersDark = window.matchMedia("(prefers-color-scheme: dark)");
      applyTheme(prefersDark.matches ? "dark" : "light");

      const listener = (e: MediaQueryListEvent) => {
        applyTheme(e.matches ? "dark" : "light");
      };
      prefersDark.addEventListener("change", listener);
      return () => prefersDark.removeEventListener("change", listener);
    } else {
      applyTheme(theme);
    }
  }, [theme]);

  const setTheme = (newTheme: Theme) => {
    setThemeState(newTheme);
    localStorage.setItem("theme", newTheme);
  };

  return (
    <ThemeContext.Provider value={{ theme, setTheme, resolvedTheme }}>
      {children}
    </ThemeContext.Provider>
  );
}

export function useTheme() {
  const context = useContext(ThemeContext);
  if (!context) throw new Error("useTheme must be used within ThemeProvider");
  return context;
}
typescript
// src/main.tsx
import { StrictMode } from "react";
import { createRoot } from "react-dom/client";
import { ThemeProvider } from "./providers/theme-provider";
import App from "./App";
import "./index.css";

createRoot(document.getElementById("root")!).render(
  <StrictMode>
    <ThemeProvider>
      <App />
    </ThemeProvider>
  </StrictMode>
);
针对更复杂的主题管理，创建自定义上下文：
typescript
// src/providers/theme-provider.tsx
import {
  createContext,
  useContext,
  useEffect,
  useState,
  type ReactNode,
} from "react";

type Theme = "light" | "dark" | "system";

interface ThemeContextType {
  theme: Theme;
  setTheme: (theme: Theme) => void;
  resolvedTheme: "light" | "dark";
}

const ThemeContext = createContext<ThemeContextType | undefined>(undefined);

export function ThemeProvider({ children }: { children: ReactNode }) {
  const [theme, setThemeState] = useState<Theme>("system");
  const [resolvedTheme, setResolvedTheme] = useState<"light" | "dark">("light");

  useEffect(() => {
    const savedTheme = (localStorage.getItem("theme") as Theme) || "system";
    setThemeState(savedTheme);
  }, []);

  useEffect(() => {
    const root = document.documentElement;
    const applyTheme = (newTheme: "light" | "dark") => {
      root.classList.remove("light", "dark");
      root.classList.add(newTheme);
      setResolvedTheme(newTheme);
    };

    if (theme === "system") {
      const prefersDark = window.matchMedia("(prefers-color-scheme: dark)");
      applyTheme(prefersDark.matches ? "dark" : "light");

      const listener = (e: MediaQueryListEvent) => {
        applyTheme(e.matches ? "dark" : "light");
      };
      prefersDark.addEventListener("change", listener);
      return () => prefersDark.removeEventListener("change", listener);
    } else {
      applyTheme(theme);
    }
  }, [theme]);

  const setTheme = (newTheme: Theme) => {
    setThemeState(newTheme);
    localStorage.setItem("theme", newTheme);
  };

  return (
    <ThemeContext.Provider value={{ theme, setTheme, resolvedTheme }}>
      {children}
    </ThemeContext.Provider>
  );
}

export function useTheme() {
  const context = useContext(ThemeContext);
  if (!context) throw new Error("useTheme必须在ThemeProvider中使用");
  return context;
}
typescript
// src/main.tsx
import { StrictMode } from "react";
import { createRoot } from "react-dom/client";
import { ThemeProvider } from "./providers/theme-provider";
import App from "./App";
import "./index.css";

createRoot(document.getElementById("root")!).render(
  <StrictMode>
    <ThemeProvider>
      <App />
    </ThemeProvider>
  </StrictMode>
);

Color Accessibility Guidelines

色彩可访问性指南

ALWAYS ensure proper contrast ratios:
  1. Normal text (< 18px): 4.5:1 contrast ratio (AA), 7:1 (AAA)
  2. Large text (≥ 18px): 3:1 contrast ratio (AA), 4.5:1 (AAA)
  3. UI components: 3:1 contrast ratio (AA)
typescript
// ✅ Good - Accessible color combinations
<div className="bg-background text-foreground">
  <Button className="bg-primary text-primary-foreground">
    Accessible Button
  </Button>
  <p className="text-muted-foreground">Accessible muted text</p>
</div>

// ❌ Bad - Poor contrast
<div className="bg-gray-100">
  <button className="bg-gray-300 text-gray-400">
    Low contrast button
  </button>
</div>
请始终确保符合对比度要求：
  1. 普通文本（<18px）：4.5:1对比度（AA标准），7:1（AAA标准）
  2. 大文本（≥18px）：3:1对比度（AA标准），4.5:1（AAA标准）
  3. UI组件：3:1对比度（AA标准）
typescript
// ✅ 推荐 - 符合可访问性的色彩组合
<div className="bg-background text-foreground">
  <Button className="bg-primary text-primary-foreground">
    可访问按钮
  </Button>
  <p className="text-muted-foreground">可访问的次要文本</p>
</div>

// ❌ 不推荐 - 对比度不足
<div className="bg-gray-100">
  <button className="bg-gray-300 text-gray-400">
    低对比度按钮
  </button>
</div>

<div className="flex min-h-screen">
  {/* Sidebar */}
  <aside className="hidden w-64 border-r bg-muted/40 lg:block">
    <nav className="flex flex-col gap-2 p-4">{/* Navigation items */}</nav>
  </aside>

  {/* Main Content */}

  <div className="py-8 md:py-12 lg:py-16">{/* 内容 */}</div>
</div>

Critical Rules

重要规则

NEVER:
  • Use inline styles (use Tailwind classes)
  • Hardcode colors (use design tokens: 
    bg-background
    , NOT 
    bg-white
    )
  • Use arbitrary color values (
    bg-[#fff]
    ) without defining tokens first
  • Skip accessibility attributes on interactive elements
  • Ignore mobile breakpoints
  • Use 
    any
    type in TypeScript
  • Create components without TypeScript interfaces
  • Forget dark mode variants (test in both light and dark modes)
  • Use fixed pixel widths for responsive elements
  • Skip semantic HTML
  • Use hardcoded hex colors that break dark mode
ALWAYS:
  • Use design tokens for ALL colors (
    bg-primary
    , 
    text-foreground
    , etc.)
  • Define custom colors as CSS variables in 
    :root
    and 
    .dark
    selectors
  • Map CSS variables to Tailwind with 
    @theme inline
  • Start with mobile-first design
  • Use shadcn/ui components when available
  • Apply 
    cn()
    utility for conditional classes
  • Include proper TypeScript types for props
  • Add ARIA attributes for accessibility
  • Test keyboard navigation
  • Provide focus states
  • Use semantic HTML elements
  • Support both light and dark modes with proper tokens
  • Ensure color contrast ratios meet WCAG AA standards (4.5:1 for text)
  • Create color scales (50-900) for brand colors
  • Use 
    color-mix()
    for surface/background variants
  • Extract reusable patterns
  • Document complex component logic
  • Follow React best practices
禁止：
  • 使用内联样式（请使用Tailwind类）
  • 硬编码色彩（请使用设计令牌：
    bg-background
    ，而非
    bg-white
    ）
  • 在未定义令牌的情况下使用任意色值（
    bg-[#fff]
    ）
  • 跳过交互元素的可访问性属性
  • 忽略移动端断点
  • 在TypeScript中使用
    any
    类型
  • 创建不带TypeScript接口的组件
  • 忘记深色模式变体（在亮色和暗色模式下均需测试）
  • 为响应式元素使用固定像素宽度
  • 跳过语义化HTML
  • 使用会破坏深色模式的硬编码十六进制颜色
必须：
  • 所有色彩均使用设计令牌（
    bg-primary
    、
    text-foreground
    等）
  • 在
    :root
    和
    .dark
    选择器中定义自定义色彩为CSS变量
  • 使用
    @theme inline
    将CSS变量映射到Tailwind
  • 从移动端优先设计开始
  • 优先使用shadcn/ui组件
  • 使用
    cn()
    工具类处理条件样式
  • 为Props添加完整的TypeScript类型
  • 添加ARIA属性以支持可访问性
  • 测试键盘导航
  • 提供焦点状态
  • 使用语义化HTML元素
  • 使用正确的令牌支持亮色和暗色模式
  • 确保色彩对比度符合WCAG AA标准（文本最小4.5:1）
  • 为品牌色彩创建50-900的色彩层级
  • 使用
    color-mix()
    创建表面/背景变体
  • 提取可复用模式
  • 为复杂组件逻辑添加文档
  • 遵循React最佳实践
