// 走秀 / 街拍详情页共享的全屏大图灯箱：大图 + 左/右翻页 + 单图收藏。
//
// 左栏「所有图片缩略图条」已移除：翻页/定位已由顶部计数 + 左右箭头 + 键盘 ←/→ + ?img= 深链完整覆盖，
// 缩略条属冗余导航；去掉后主图可用面积更大。主图翻页实际读的是图集网格里 [data-image-index] 的
// figure（第 6 张起的 extraImages 也已在网格里渲染），与左栏无关，故移除不影响翻页。
//
// 视觉遵循全站「黑白编辑风」：直角细框、小字 + 宽字距、零填充计数、hover 反色（bg-black + 白字）。
// 交互逻辑全部在 src/lib/gallery.ts（createGalleryView）；本组件只负责标记。
//
// 各页独有的附加层通过具名插槽 details 注入（走秀页塞「当前 look 的细节图簇」，街拍页不传）。
