📱 用法：点任意一张 → 进入全景：拖动环顾四周，双指缩放；手机上点右上角的指南针/陀螺仪按钮，然后举着手机转身——你就站在照片拍摄的那个位置了（iPhone 会先弹一次授权，点允许）。
📱 How to use: tap any tile → inside the panorama: drag to look around, pinch to zoom; on a phone tap the compass/gyro button (top right), then physically turn with your phone — you're standing where the shot was taken (iPhone asks permission once).
