// spotlight-hero-card —— 聚光灯锁定一张卡 → 斜 45° 推进 → 卡片弹起悬浮 →
// 轮廓光束两圈 → 贴回原位。单一主角式产品开场，把核心对象立成全片主角。
// 参考实现从 template SceneOpen 的 82–220 段剥离，self-contained：
// 游走聚光灯经 4 个中间站后锁定卡心（光池收拢 + 锁定脉冲 + vignette 压暗）；
// 相机全页正视 → 16f 斜侧推进（rotY 34° 主导 + rotX 8°）；卡 rise（带过冲）→
// 悬停 sin bob（54f）→ reseat（18f 落地微压）；SVG rounded-rect 轮廓光束两圈
// （lap1 快而亮 / lap2 慢而弱）；悬停期左侧 3D 注记 + 马克笔荧光条。
// 主角卡 = layout.projects.cards[3]，中心 x 恰为 960（页面中心）。
