fix: 修复所有板块 pin 滚动空白间隙 + 服务卡片适配屏幕
🐛 问题1: 滚动到下一个内容时有空白区 根因: 时间线动画之间有间隙(动画 duration < 步骤间距) 修复: 所有板块改用 cursor 模式,每个步骤精确衔接,无空白 🐛 问题2: 服务卡片太大,一屏显示不全 根因: 卡片高度固定 h-[380px],不适配小屏幕 修复: 改用 clamp(260px, 38vh, 400px) 自适应屏幕高度 🔧 修复的 6 个板块: 1. HomeTestimonials - 淡入淡出切换无间隙 2. HomeServices - 卡片聚焦无间隙 + 自适应高度 3. HomeAchievements - 数字展示无间隙 4. HomeTechStack - 球体旋转无间隙 5. HomeProcess - 步骤展示 + 横向滚动无间隙 6. HomeUpdates - 卡片分批出现无间隙 📐 cursor 模式: 每一步动画 duration 正好等于步骤间距, 动画结束 = 下一步开始,完美衔接 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
