 - 本地图片烟测已生成查歌 `136`、查活动 `50` 简易背景和真实活动背景图片，证明 provider/repository 第一段迁移后仍能输出非空图片。
 - 已新增 `models/song-resource-repository.ts`，把 `Song` 的歌曲详情、谱面、封面路径、封面完整 URL 和封面缺失时服务器回退下载收口到不依赖 `Song` 类的资源 repository，避免 `song.ts` 继续直接拼 Bestdori API/asset 路径；`song-resource-repository.spec.ts` 覆盖 detail/chart provider 调用、13/40 旧封面批次、273 强制 CN 和封面 fallback 行为，本地 `/查曲 136`、`/查谱面 136 expert` 图片 smoke 输出非空。
