+# Task: 支持 AI 设计输入框回车发送
+
+## Identity
+
+- Task ID: 20260806-design-enter-send-b83f
+- Mode: Feature
+- Branch: codex/design-enter-send-b83f
+- Worktree: D:\Datas\OthersProjects\makelore-design-enter-send-b83f
+- Base commit: 7b23cce67a1b9e61a48d89dedbd088d37b10ecd4
+- Owner: codex
+- Status: Completed
+
+## Scope
+
+- 让 AI 设计输入框在非输入法组合状态下按 Enter 直接发送。
+- 保留 Shift+Enter 输入换行，并同步更新快捷键提示。
+- 增加回车发送、换行和输入法保护的回归测试。
+
+## Intent And Constraints
+
+- 复用现有 `handleSend`，不改变消息、Quote 确认与任务创建链路。
+- 中文输入法候选确认期间的 Enter 不得误发消息。
+- 改动仅限 AI 设计页及其聚焦测试，不触碰原主工作区中的未归属改动。
+
+## Plan
+
+1. 调整输入框键盘事件判定与可见快捷键提示。
+2. 覆盖 Enter、Shift+Enter 和 IME composition 三种行为。
+3. 执行聚焦测试、类型检查、Lint 与 Vite 构建。
+
+## Outcome
+
+- AI 设计输入框现在按 Enter 即可发送，继续复用既有消息与结构化 Quote 确认逻辑。
+- Shift+Enter 保留多行输入；输入法组合状态下按 Enter 不会误发。
+- 输入框下方提示已更新为 `Enter 发送 · Shift+Enter 换行`。
+
+## Verification
+
+- `vitest run tests/unit/image-canvas-page.test.tsx`：21 passed。
+- `tsc --noEmit`：通过。
+- `eslint src/pages/ImageCanvas/index.tsx tests/unit/image-canvas-page.test.tsx`：通过。
+- `vite build`：通过，仅有既有动态导入与 chunk 体积警告。
+- 全仓 `eslint .`：未通过，命中本任务之外的既有问题：`src/components/layout/MainLayout.tsx` effect 内同步 setState、`tests/unit/chat-command-dialogs.test.tsx` 未使用变量，以及 6 个既有 warning。
+
+## Follow-ups
+
+- 后续可单独清理全仓既有 Lint 基线问题，不阻塞本次交互修复。
+
+## Promotion Candidates
+
+- None recorded.
