- Workbench.tsx 937→467 行，抽出 AiToolbar/WorkbenchToolbar/MobileContextBar - P3-3 AI 工具条分组留白 + 眉题 + 主 CTA 凸显 - P3-4 专注写作模式（useFocusMode hook+vitest，隐藏侧栏加宽正文）+ 左双栏面色区分 - P3-5 右栏本章参考小标题去衬线(font-sans) + 空态引导(无标题保 h2→h3 大纲) - P3-6 底栏信息/操作/状态三区 + TOC 当前章高亮；TOC 状态点因无每章状态数据跳过 - P3-7 展示层流式跟随滚动（不触碰 SSE 逻辑，尊重 reduced-motion） - AppShell 加可选 hideNav（加法式，默认 false）
