feat: 为首页新增板块添加 ScrollTrigger pin 滚动效果
✨ 新增 pin 效果(板块固定,内容随滚动切换): 1. HomeTestimonials - 客户评价 - 固定板块,滚动自动切换卡片 - 每屏切换一张评价卡片 2. HomeTechStack - 技术栈 - 固定板块,3D 球体自动旋转一圈 - 滚动控制旋转进度 3. HomeProcess - 创意流程 - 固定板块,横向滚动浏览所有步骤 - 6 个步骤依次展示 4. HomeServices - 服务能力 - 固定板块,逐张卡片聚焦展示 - 聚焦卡片放大,其他缩小变暗 - 所有卡片飞入归位后逐个聚焦 5. HomeAchievements - 数字成就 - 固定板块,逐个成就项展示 - 每个数字滚动计数动画触发 6. HomeUpdates - 最新动态 - 固定板块,逐批展示卡片 - 分批出现,每批 3 个卡片 🎯 效果: - 滚动到板块时自动固定(pin) - 内部元素随滚动依次展示 - 所有内部元素展示完毕后才继续下一个板块 - 每个板块独特的 pin 动画效果 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
