fix(model-picker): 模型选择 - 修复候选报价显示与同渠道模型跳回

 - [x] 前端生产构建通过，修复镜像已部署；首页、创作台路由、入口资源和创作台脚本与本次构建逐字节一致，容器健康与 API 就绪检查通过。构建仍提示部分 chunk 超过 500 kB。
 - [ ] 在真实创作台使用万有引力渠道的 `minimax-h3-a`，输入“小猫在流泪”，选择 `16:9`、`480P`，检查报价、首次生成和失败后重试；同时确认支持同步音频的模型遵循各自默认值。本次不调用真实上游，生成结果仍待验收。
 
+## 模型候选价目与同渠道独立选择
+
+- [x] 候选模型列表展示自身配置的价格或多规格价格范围，不再使用当前模型的分辨率、时长等参数判定其他候选模型「无报价」。选中模型的触发器、请求估价仍按当前参数精确匹配；未配置价格不显示为免费。
+- [x] 平台直连模型以渠道 ID 和模型 Key 保持独立，同渠道同展示名不再合并成自动选价模型族。选择、生成请求和报价保留用户选中的模型，不再借用同名模型的参考输入上限；个人渠道原有细分模型兼容路由保持不变。
+- [x] 58 项专项及相邻测试通过，覆盖同渠道同名不同价模型的选择、实际生成配置、报价目标、能力隔离，以及真实价格组件的明暗主题静态渲染；前端类型检查和生产构建通过。构建仍提示部分 chunk 超过 500 kB。
+- [ ] 云端部署前端后，在真实 MiniMax H3 列表逐项切换高速版、多图一致性、音画融合及满血等选项，确认选中项不跳回、价目与后台一致；调整参数后检查精确报价和实际任务使用的渠道与模型。本轮未读取云端配置或日志、未调用真实付费生成、未部署，静态渲染不代表云端端到端验收完成。
+
 ## 多模态列表与分镜表合并回归
 
 - [x] 合入 PR #549 的图片 / 视频列表分析、动态表格、视频脚本转换和批量生成设置；参考图上限前后端统一为 10。保留本地主分支表格布局、参考图提及、删除列、结果定位、手工行增量同步及单行重新生成。
