根因：useTitleCoverSync 的 useEffect 依赖 userTemplates（每次渲染 .filter() 生成新数组引用），导致： 用户拖滑块 → setState → 重渲染 → 新数组引用 → effect 触发 → 从模板 title_config.font_size 覆盖回去 → slider 回弹 修复1（核心）：useTemplateSelection.ts 用 useMemo 缓存 validTemplates， 仅在 allTemplates 变化时重新计算，稳定下游引用。 修复2（防御性）：useTitleCoverSync.ts 用 ref 持有 userTemplates， 从依赖数组移除，effect 只在 selectedTemplate 真正变化时触发。 |
