1) 照片与附件不再新开窗口看 之前点缩略图直接 target=_blank 打开原始文件，看完还得切回来。 现在统一走当前页灯箱（templates/_lightbox.php，详情页照片墙与 照片管理页共用）：左右箭头 / 键盘 ←→ / 手机滑动切上一张下一张， Esc 或点背景关闭，带「第几张 / 共几张」计数并预加载相邻两张。 非图片附件（PDF 等）仍保留直接打开与下载。 2) 参与人可以直接改了 之前加完只能移出重加。现在每个参与人旁有「编辑」，点开预填弹窗 （角色标签 / 心情 / 签到时间），保存仍走 members/store —— Members::save() 本来就是 upsert（同节点同人一条），服务端零改动。 失败回填按 user_id 精确匹配，只回填刚才没保存成的那个人。 3) 花销去掉预算，只记真实花费 明细上移，底部一行「总计（N 笔）¥X」。表单不再有「预算」选项， 查询一律 is_budget=0（历史预算行不再出现在列表与合计里）； 活动页统计同步改成「共 N 笔 · 总计」。列保留在库里不删数据。 已验证：本地全链 11 步全绿（php -l / 渲染 286 项 / SQL / PDO / CSS / Mime / amap / 内联 JS×11 / 布局几何 / 表单交互 73 项）；远端 e2e 296 项 0 失败（含灯箱、编辑弹窗、历史预算行排除的专项断言）； 部署后双 PHP 渲染逐字节一致、60 文件哈希一致，线上 style.css 含新规则。
