- 视频生成积分规则：从按对口型实际时长计费改为按脚本规划总时长计费 - 前端 VideoGeneration：提交 lipSync 时传 plannedDuration + totalPlannedDuration + batchId - 后端 video_handler：tick 预检用 planned_duration，扣费改为总时长一次性扣 + batch_id 幂等 - 后端 tasks.py：VideoParams 替换字段，余额检查用 planned_duration - 前端按钮旁显示预计消耗积分 - 新增 errorMessage.ts：统一错误信息友好化转换 - ScriptCreation/VideoGeneration/VoiceSynthesis/SubtitleBurning/CoverDesign：弹窗错误文案改用友好提示 - ProgressModal.css：错误/成功文案添加折行样式 - ContentManagement.css：补全缺失的 settings-row 样式 - ScriptCreation：删除过时空状态文案和多余 Slider.css import
