/* ═════ 08 报告页 —— 1:1 移植 H5 #s-report ═════
   数据来源不变：utils/report-model.js 的 model()/layers()/marks()（接口未改），
   本文件只做 H5 版面映射：
     1) 七个检测视角按 H5 的三张维度卡分组（紧塑力 2 / 透亮感 3 / 稳韧力 2）；
     2) H5 SVG 环形评分 → conic-gradient 角度 + 圆头补点（acss 无 svg）；
     3) H5 app.js vizFaceCrop/vizCompose 的人脸裁切窗口 → 照片与 face_maps 图层共用的
        「同一画框绝对定位」，保证叠加层位置与 H5 canvas 合成一致；
     4) 痘/斑标记坐标：接口像素坐标 → 画框百分比（含 H5 的最小框放大规则）；
     5) 侧脸皱纹标注：payload.wrinkle_job + api.wrinkleViews，pending/unavailable 文案同 H5。 */
