# 睿新致远官网重构实施计划

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**Goal:** 基于优秀案例参考，全面升级睿新致远官网，融合印章文化与现代科技，提升品牌形象和转化率

**Architecture:** 采用 Next.js 16 App Router + React 19 + TypeScript 技术栈，基于现有组件库扩展，优化 Hero 区域印章动画，新增技术洞察板块和客户评价模块，全面提升用户体验和转化路径

**Tech Stack:** Next.js 16.1.6, React 19.2.3, TypeScript 5, Tailwind CSS v4, Framer Motion 12.29.2, shadcn/ui

---

## 实施策略

### 优先级说明

**P0（核心功能）** - 必须完成，直接影响品牌形象和转化
**P1（重要功能）** - 显著提升用户体验和专业度
**P2（增强功能）** - 锦上添花，可后续迭代

### 开发原则

- **TDD（测试驱动开发）**：先写测试，再写实现
- **DRY（不重复）**：复用现有组件和工具函数
- **YAGNI（不过度设计）**：只实现当前需要的功能
- **频繁提交**：每个小功能点独立提交
- **性能优先**：关注 LCP、FID、CLS 指标

## Phase 1: P0 核心功能优化（预计 5-7 天）

### Task 1: 优化印章粒子动画组件

**目标：** 增强印章粒子动画的视觉效果和交互体验

**Files:**
- Modify: `src/components/effects/seal-particle.tsx`
- Create: `src/components/effects/seal-animation-enhanced.tsx`
- Test: `src/components/effects/__tests__/seal-animation-enhanced.test.tsx`

**Step 1: 创建增强版印章动画组件**

创建文件：`src/components/effects/seal-animation-enhanced.tsx`

    const centerY = height / 2;
    const sealSize = Math.min(width, height) * 0.35;
    const particles: { x: number; y: number }[] = [];

    // 创建印章形状的粒子位置（简化版方形印章）
    for (let i = 0; i < particleCount; i++) {
      const angle = (i / particleCount) * Math.PI * 2;
      const radius = sealSize * (0.8 + Math.random() * 0.4);
      particles.push({
        x: centerX + Math.cos(angle) * radius * (Math.random() > 0.5 ? 1 : 0.8),

      const size = 2 + Math.random() * 3;
      const maxLife = 200 + Math.random() * 100;

      return {
        x,
        y,
        targetX,
        targetY,
        vx: (Math.random() - 0.5) * 2,
        vy: (Math.random() - 0.5) * 2,
        size,
        opacity: 0.6 + Math.random() * 0.4,
        color,
        life: 0,
        maxLife,
        stage: 'idle',
      };
    },
    [colors]
  );

  useEffect(() => {
    const canvas = canvasRef.current;
    if (!canvas) return;

    const ctx = canvas.getContext('2d');
    if (!ctx) return;

    canvas.width = width;
    canvas.height = height;

    const sealPositions = createSealShape(width, height);
    particlesRef.current = sealPositions.map((pos, i) =>
      createParticle(pos.x, pos.y, pos.x, pos.y)
    );

    // 动画阶段控制
    if (animationStages) {
      // 3秒后开始分散
      stageTimerRef.current = setTimeout(() => {
        setCurrentStage('dispersing');
        onStageChange?.('dispersing');
        
        particlesRef.current.forEach(p => {
          p.vx = (Math.random() - 0.5) * 4;
          p.vy = (Math.random() - 0.5) * 4;
          p.stage = 'dispersing';
        });

        // 2秒后开始重组
        setTimeout(() => {
          setCurrentStage('reforming');
          onStageChange?.('reforming');
          
          particlesRef.current.forEach(p => {
            p.stage = 'reforming';
          });

          // 3秒后回到idle
          setTimeout(() => {
            setCurrentStage('idle');
            onStageChange?.('idle');
          }, 3000);
        }, 2000);
      }, 3000);
    }

    const animate = () => {
      ctx.clearRect(0, 0, width, height);

      particlesRef.current.forEach((particle) => {
        if (particle.stage === 'reforming') {
          // 向目标位置移动
          const dx = particle.targetX - particle.x;
          const dy = particle.targetY - particle.y;
          particle.vx += dx * 0.02;
          particle.vy += dy * 0.02;
          particle.vx *= 0.95;
          particle.vy *= 0.95;
        }

        particle.x += particle.vx;
        particle.y += particle.vy;
        particle.life++;

        // 绘制粒子
        ctx.beginPath();
        ctx.arc(particle.x, particle.y, particle.size, 0, Math.PI * 2);
        ctx.fillStyle = particle.color;
        ctx.globalAlpha = particle.opacity;
        ctx.fill();
        ctx.globalAlpha = 1;
      });

      animationRef.current = requestAnimationFrame(animate);
    };

    animate();

    return () => {
      if (animationRef.current) {
        cancelAnimationFrame(animationRef.current);
      }
      if (stageTimerRef.current) {
        clearTimeout(stageTimerRef.current);
      }
    };
  }, [width, height, createSealShape, createParticle, animationStages, onStageChange]);

  return (
    <canvas
      ref={canvasRef}
      className={className}
      style={{ width, height }}
    />
  );
}
```

**Step 2: 创建测试文件**

创建文件：`src/components/effects/__tests__/seal-animation-enhanced.test.tsx`

```typescript
import { render, screen } from '@testing-library/react';
import { SealAnimationEnhanced } from '../seal-animation-enhanced';

describe('SealAnimationEnhanced', () => {
  it('should render canvas element', () => {
    render(<SealAnimationEnhanced />);
    const canvas = screen.getByRole('img');
    expect(canvas).toBeInTheDocument();
  });

  it('should accept custom props', () => {
    const { container } = render(
      <SealAnimationEnhanced
        width={400}
        height={400}
        particleCount={200}
        colors={['#FF0000', '#00FF00']}
        sealText="测试"
        animationStages={false}
      />
    );
    const canvas = container.querySelector('canvas');
    expect(canvas).toHaveAttribute('width', '400');
    expect(canvas).toHaveAttribute('height', '400');
  });

  it('should call onStageChange callback', (done) => {
    const handleStageChange = (stage: string) => {
      expect(stage).toBe('dispersing');
      done();
    };

    render(
      <SealAnimationEnhanced
        animationStages={true}
        onStageChange={handleStageChange}
      />
    );
  });
});
```

**Step 3: 运行测试**

```bash
npm test src/components/effects/__tests__/seal-animation-enhanced.test.tsx
```

Expected: PASS

**Step 4: 提交代码**

```bash
git add src/components/effects/seal-animation-enhanced.tsx
git add src/components/effects/__tests__/seal-animation-enhanced.test.tsx
git commit -m "feat: add enhanced seal animation component with stages"
```

### Task 2: 更新 Hero Section 使用增强版印章动画

**目标：** 在 Hero 区域集成增强版印章动画，提升视觉冲击力

**Files:**
- Modify: `src/components/sections/hero-section.tsx`
- Create: `src/lib/constants.ts` (如果不存在)

**Step 1: 检查并创建 constants 文件**

检查文件是否存在：`src/lib/constants.ts`

如果不存在，创建：

```typescript
export const COMPANY_INFO = {
  name: '睿新致远',
  slogan: '以技术创新，铸就卓越未来',
  description: '专注于数字化转型与技术创新，为企业提供全方位的技术解决方案',
  foundedYear: 2014,
  teamSize: '50+',
};

export const STATS = [
  { value: '10+', label: '年技术积累' },
  { value: '200+', label: '成功案例' },
  { value: '50+', label: '技术专家' },
  { value: '99.5%', label: '客户满意度' },
];

export const NAV_LINKS = [
  { href: '#home', label: '首页' },
  { href: '#solutions', label: '解决方案' },
  { href: '#cases', label: '成功案例' },
  { href: '#about', label: '关于我们' },
  { href: '#contact', label: '联系我们' },
];
```

**Step 2: 更新 Hero Section**

修改文件：`src/components/sections/hero-section.tsx`

在文件顶部添加导入：

```typescript
import { SealAnimationEnhanced } from '@/components/effects/seal-animation-enhanced';
```

在 Hero Section 组件中，找到现有的 `SealParticle` 组件，替换为：

```typescript
{/* 增强版印章动画 */}
<div className="absolute right-0 top-1/2 -translate-y-1/2 hidden lg:block">
  <SealAnimationEnhanced
    width={400}
    height={400}
    particleCount={150}
    colors={['#C41E3A', '#D4A574', '#8B4513']}
    sealText="睿新"
    animationStages={true}
    onStageChange={(stage) => console.log('Animation stage:', stage)}
    className="opacity-80"
  />
</div>
```

**Step 3: 测试更新后的 Hero Section**

```bash
npm run dev
```

访问 http://localhost:3000，检查：
- 印章动画是否正常显示
- 动画阶段是否按预期切换（idle → dispersing → reforming → idle）
- 移动端是否隐藏动画（lg:block）

**Step 4: 提交代码**

```bash
git add src/components/sections/hero-section.tsx
git add src/lib/constants.ts
git commit -m "feat: integrate enhanced seal animation in hero section"
```
