- 专注内输入条 —— 滚动到对话最底部时自动展开精简输入框，与主输入框共享同一份草稿（进专注前打的字就在里面，退出后草稿仍在）；
Enter发送、Shift+Enter换行，AI 忙时自动排队（显示排队数）；有草稿时点击对话区域自动收起为带蓝点的圆钮，一键展开续写。
In-focus composer — the compact input bar appears at the live edge and shares the main composer's draft (text typed before entering focus is already there, and survives on exit). Enter sends, Shift+Enter newlines, messages queue while the AI runs (with a queued-count chip); with a draft, clicking the conversation folds the bar into a blue-dot pill, one click to expand. - 专注内作答 —— AI 提问 / 审批等待时，「去回答」原地展开答题卡：单选编号选项、多选复选框、可选自由文本、允许 / 拒绝审批，提交即继续，全程无需退出专注模式。
In-place answers — a pending question or approval expands into an answer card (numbered single-select options, multi-select checkboxes, optional free text, allow/deny approvals); submit and the AI continues, without ever leaving focus mode. - 官方视觉统一 —— 输入条 / 答题卡 / 圆钮 / ↓ 按钮全部采用官方输入控件的设计令牌与图标（input-major 表面、22px 圆角、34px 圆形发送按钮、IconEdit / IconSend 图标系）。
Official visual language — the bar, answer card, pill and jump button now mirror the official composer's design tokens and icon set (input-major surfaces, 22px radii, the 34px round send button, IconEdit / IconSend glyphs). - Esc 逐层退出 —— 答题卡 → 输入条 → 专注模式，一层一层剥；输入法组合中的按键不会误触。
Layered Esc — answer card → input bar → exit focus mode, one layer at a time; IME-composition keypresses never trigger it (Safari included).
