+```
+
+Rules:
+- Thumbnail should not dominate vertical space.
+- Keep Naive UI theming and avoid hardcoded light-only backgrounds.
+
+- [ ] **Step 4: Split “detected current prompt” into its own section**
+
+Implementation direction:
+
+```vue
+
+ {{ t('imageWorkspace.referenceImage.detectedCurrentPromptTitle') }}
+
+ {{ referenceDialog.detectedOriginalPromptPreview }}
+
+
+```
+
+Rules:
+- Show only preview text visually via CSS line clamp.
+- Do not place it under the usage-mode heading.
+
+- [ ] **Step 5: Convert the mode selector into user-facing option cards**
+
+Implementation direction:
+
+```vue
+
+
+
+
+
+```
+
+Rules:
+- Preserve the underlying radio semantics.
+- Increase selection clarity with border/background states derived from theme tokens.
+
+- [ ] **Step 6: Move the result area to a mixed layout**
+
+Implementation direction:
+
+```vue
+
+ ...
+ ...
+
+```
+
+Rules:
+- Desktop: `2fr / 1fr`
+- Narrow widths: stack vertically
+- Prompt textarea gets a stable minimum height
+- Variable list gets a stable min/max height with scrolling
+
+- [ ] **Step 7: Remove the undo banner from the workspace**
+
+Delete:
+- success alert block above the template/model controls
+- `handleReferenceDialogUndo` wiring
+- any `referenceDialog.canUndoLastApply` template branches
+
+- [ ] **Step 8: Re-run the UI source guard test**
+
+Run:
+
+```powershell
+pnpm -F @prompt-optimizer/ui test -- tests/unit/image/reference-image-theme-guards.spec.ts
+```
+
+Expected:
+- PASS
+
+- [ ] **Step 9: Commit**
+
+```powershell

+### Task 3: Update Dialog Copy Across Locales
+
+**Files:**
+- Modify: `packages/ui/src/i18n/locales/zh-CN.ts`
+- Modify: `packages/ui/src/i18n/locales/zh-TW.ts`
+- Modify: `packages/ui/src/i18n/locales/en-US.ts`
+
+- [ ] **Step 1: Add a failing check in the UI source guard or locale-aware test**
+
+If no locale test exists, extend the existing source guard to assert the new translation keys are referenced and old ones are gone.
+
+Example:
+
+```ts
+expect(source).toMatch(/styleTransfer/)
+expect(source).toMatch(/replicateImage/)
+expect(source).not.toMatch(/migrateToCurrentPrompt/)
+expect(source).not.toMatch(/replicateOnly/)
+```
+
+- [ ] **Step 2: Run the relevant test file**
+
+Run:
+
+```powershell
+pnpm -F @prompt-optimizer/ui test -- tests/unit/image/reference-image-theme-guards.spec.ts
+```
+
+Expected:
+- FAIL until the component and locale keys agree.
+
+- [ ] **Step 3: Update the locale entries**
+
+Chinese target copy:
+
+```ts
+styleTransfer: "风格迁移",
+styleTransferDescription: "在原提示词的基础上学习图片风格进行改造",
+replicateImage: "复刻图片",
+replicateImageDescription: "丢弃原始提示词内容，反推图片对应提示词",
+detectedCurrentPromptTitle: "检测到当前提示词",
+```
+
+Also remove:
+- `undoBanner`
+- `undo`
+- `undoSuccess`
+
+- [ ] **Step 4: Keep cross-locale parity**
+
+Do not leave `zh-TW` and `en-US` behind even if the main product language is Chinese.
+
+- [ ] **Step 5: Re-run the UI test**
+
+Run:
+
+```powershell
+pnpm -F @prompt-optimizer/ui test -- tests/unit/image/reference-image-theme-guards.spec.ts

+- Test: `packages/ui/tests/unit/services/ImageStyleExtractor.reference-migration.spec.ts`
+
+- [ ] **Step 1: Add a failing service test for the 5-variable cap**
+
+Example:
+
+```ts
+it('caps extracted variables at 5 entries', async () => {
+ const result = await extractPromptVariables({
+ prompt: SOME_PROMPT,
+ modelKey: 'text-model',
+ variableExtractionService: {
+ extract: vi.fn().mockResolvedValue({
+ variables: Array.from({ length: 7 }, (_, index) => ({
+ name: `变量${index + 1}`,
+ value: `值${index + 1}`,
+ position: { originalText: `词${index + 1}`, occurrence: 1 },
+ reason: 'test',
+ })),
+ }),
+ } as any,
+ })
+
+ expect(Object.keys(result.variableDefaults)).toHaveLength(5)
+})
+```
+
+- [ ] **Step 2: Run the reference-migration service tests**
+
+Run:
+
+```powershell
+pnpm -F @prompt-optimizer/ui test -- tests/unit/services/ImageStyleExtractor.reference-migration.spec.ts
+```
+
+Expected:
+- FAIL because no hard cap exists yet.
+
+- [ ] **Step 3: Tighten the variable-extraction prompt templates**
+
+Chinese and English template changes should:
+- reduce max variable count from 20 to 5
+- instruct the model to prioritize subject, count, color, key action, and key scene/style anchor
+- avoid low-value decorative fragments
+
+Example rule block:
+
+```ts
+- 最多返回5个变量，按重要性排序
+- 优先保留主体、数量、颜色、关键动作、关键场景或核心风格锚点
+- 避免提取低价值修饰词、重复限定词和局部装饰
+```
+
+- [ ] **Step 4: Add a hard-cap safeguard in `ImageStyleExtractor.ts`**
+
+Implementation direction:
+
+```ts
+const MAX_REFERENCE_DIALOG_VARIABLES = 5
+
+const limitedVariables = result.variables.slice(0, MAX_REFERENCE_DIALOG_VARIABLES)
+const variableizedPrompt = replaceExtractedVariablesInPrompt(prompt, limitedVariables)
+const keptVariableNames = scanVariablesFromValue(variableizedPrompt)
+
+return {
+ prompt: variableizedPrompt,
+ variableDefaults: buildFilteredDefaultsFromExtractedVariables(keptVariableNames, limitedVariables),
+ rawText,
+}
+```
+
+- [ ] **Step 5: Re-run the service tests**
+
+Run:
+
+```powershell
+pnpm -F @prompt-optimizer/ui test -- tests/unit/services/ImageStyleExtractor.reference-migration.spec.ts
+```
+
+Expected:
+- PASS

+```
+
+---
+
+## Notes for the Implementer
+
+- Do not reintroduce “sync variables” or “undo once” under new names.
+- Keep the modal built on Naive UI primitives and theme tokens.
+- Prefer CSS line-clamp or constrained container height for current-prompt preview rather than trimming the underlying source text aggressively.
+- Keep the three-stage service architecture intact; this plan is a UI and policy refinement, not a pipeline rewrite.
+- If the workspace file becomes too hard to reason about, it is acceptable to extract a small presentational subcomponent for the mode cards or result grid, but only if it reduces complexity instead of spreading it.

+# 文生图参考图弹窗重构设计
+
+## 背景
+
+当前文生图中的“参考图”弹窗已经接入三段式内部链路：
+
+1. `ReferenceSpec` 提取
+2. `PromptDraft` 生成或迁移
+3. `VariableizedPrompt` 抽取
+
+但当前交互仍存在几个明显问题：
+
+- 弹窗承担了过多“临时补救”职责，例如应用后撤销，导致状态复杂度偏高。
+- “检测到当前提示词”被放在“怎么使用这张参考图”内部，信息层级不清晰。
+- 模式命名偏实现视角，用户第一眼难以理解差异。
+- 参考图预览区域占用空间过大，挤压了真正重要的结果编辑区。
+- 变量区缺少明确产品边界，当前结果更像调试信息而不是可确认的产物。
+- 当前变量提取策略过于宽松，不适合参考图迁移场景，容易抽出过多变量。
+
+本次重构目标不是新增更强的自动能力，而是把参考图弹窗整理成一个更清晰、更可理解、更可确认的前置改造流程。
+
+## 目标
+
+### 产品目标
+
+- 让用户能快速理解“这张参考图会怎么影响当前提示词”。
+- 保持现有 `文生图 / 图生图` 一级入口和模板下拉不变。
+- 让“参考图”成为清晰的前置改造工具，而不是半自动编辑器。
+- 保留 prompt 与变量的人工微调能力，但删除不必要的状态补丁和联动复杂度。
+
+### 交互目标
+
+- 让弹窗第一眼就能看懂当前上下文、可选模式和最终结果。
+- 把视觉重心从“参考图展示”转移到“生成后的提示词”和“变量预览”。
+- 让模式命名直接对应用户心智，而不是内部实现术语。
+
+### 技术目标
+
+- 删除撤销链路及其相关状态。
+- 保持三段式架构不变，只收敛 UI 结构、文案与变量策略。
+- 把变量数量稳定控制在 5 个以内，并保证优先级一致。
+
+## 非目标
+
+- 不修改图生图工作区。
+- 不新增收藏、URL、Garden 导入等参考来源。
+- 不引入 prompt 与变量的实时双向同步。
+- 不把参考图弹窗演化为 JSON 树编辑器或多步向导。
+- 不改变现有优化按钮、模板选择、主工作区链路。
+
+## 设计原则
+
+### 1. 参考图是来源，不是主角
+
+参考图用于确认风格来源是否正确，不应该占据大块主编辑空间。默认展示应为缩略图，而不是大图卡片。
+
+### 2. 先交代上下文，再让用户做选择
+
+“检测到当前提示词”属于系统当前上下文，应先独立告知用户，再让用户选择如何使用参考图。
+
+### 3. 模式命名必须是用户语言
+
+模式名称应直接表达结果差异，而不是实现逻辑。用户要看懂“风格迁移”和“复刻图片”，而不是推断“保留当前内容”和“按参考图生成”的含义。
+
+### 4. 结果区是弹窗的视觉中心
+
+弹窗应把主要空间分配给最终会被应用的两类结果：
+
+- 生成后的提示词
+- 提取到的变量
+
+### 5. 简化优先于强一致
+
+本期保留“初次生成时自动抽变量，之后允许手动改 prompt 和变量值”的弱一致策略，不引入自动重算或手动同步动作。
+
+## 方案比较
+
+### 方案 A：纯纵向堆叠
+
+按顺序纵向排列所有内容块：
+
+- 参考图
+- 检测到当前提示词
+- 使用方式
+- 生成后的提示词
+- 变量预览
+
+优点：
+
+- 实现简单
+- 信息顺序线性
+
+缺点：
+
+- 弹窗过长
+- 重点区域不够突出
+- prompt 与变量缺少工作台感
+
+### 方案 B：完全左右双栏
+
+整个弹窗采用左右布局，把上下文和结果一起放入双栏。
+
+优点：
+
+- 可在桌面端压缩高度
+- 对比感更强
+
+缺点：
+
+- 信息关系变复杂
+- 辅助信息和核心结果抢空间
+- 响应式和主题适配更容易出问题
+
+### 方案 C：上轻下重的混合布局
+
+顶部为轻量上下文区，中部为模式选择，底部为结果工作区双栏。
+
+结构为：
+
+- 顶部：`参考图` 缩略图卡 + `检测到当前提示词` 摘要卡
+- 中部：`风格迁移 / 复刻图片` 两张模式卡
+- 底部：左侧 `生成后的提示词`，右侧 `提取到的变量`
+
+优点：
+
+- 信息优先级清晰
+- 结果区获得足够空间
+- 比纯双栏更稳，比纯纵向更紧凑
+
+缺点：
+
+- 需要对弹窗结构和样式做一次性整理
+
+### 推荐方案
+
+采用方案 C。它最符合当前产品定位，也最容易沿用 Naive UI 和现有弹窗结构做稳定落地。
+
+## 信息架构
+
+### 1. 参考图
+
+作为第一块区域展示，采用缩略图样式：
+
+- 左侧固定尺寸缩略图，建议 `96x96` 或 `112x112`
+- 右侧展示文件名、说明文字和“上传/更换图片”按钮
+- 默认不展示大图，不占用额外垂直空间
+- 点击缩略图时可沿用现有图片预览能力，但不作为默认状态
+
+说明文案继续保留：
+
+- `仅支持本地 PNG/JPEG，最大 10MB`
+
+### 2. 检测到当前提示词
+
+仅在当前原始提示词非空时显示，作为独立信息卡片放在参考图区域之后。
+
+展示规则：
+
+- 标题：`检测到当前提示词`
+- 只展示前 2 到 3 行摘要
+- 超出内容省略，不展示完整正文
+- 目的仅为帮助用户判断是否保留当前内容，避免把遗留文本误当成当前意图
+
+该区域不承担编辑功能。
+
+### 3. 怎么使用这张参考图
+
+作为单独区域展示，不再混入当前提示词信息。
+
+模式命名改为：
+
+- `风格迁移`
+- `复刻图片`
+
+模式说明改为：
+
+- `风格迁移`：在原提示词的基础上学习图片风格进行改造
+- `复刻图片`：丢弃原始提示词内容，反推图片对应提示词
+
+展示方式：
+
+- 使用可点击卡片承载单选逻辑，而不是仅显示普通文字型 radio
+- 卡片需有明显选中态，便于第一眼区分
+
+规则：
+
+- 当前提示词为空时，不显示模式切换，默认只走 `复刻图片`
+- 当前提示词非空时，默认推荐 `风格迁移`
+
+## 弹窗布局
+
+### 桌面端
+
+采用混合布局：
+
+- 顶部上下文区：纵向排列两个轻量卡片
+ - `参考图`
+ - `检测到当前提示词`
+- 中部模式区：两张模式卡横向排布
+- 底部结果区：左右布局
+ - 左：`生成后的提示词`，宽度约 `2fr`
+ - 右：`提取到的变量`，宽度约 `1fr`
+
+### 窄屏
+
+底部结果区自动回退为纵向堆叠：
+
+- 先显示 `生成后的提示词`
+- 再显示 `提取到的变量`
+
+### 弹窗尺寸
+
+- 继续基于 Naive UI `NModal + NCard`
+- 控制整体宽度，不允许回退为异常全屏
+- 建议桌面宽度保持在 `min(880px, calc(100vw - 32px))` 左右的级别
+- 保持主题跟随，避免硬编码浅色背景或阴影逻辑
+
+## 结果编辑区设计
+
+### 生成后的提示词
+
+这是弹窗的主内容区，应具备稳定高度。
+
+规则：
+
+- 使用单个可编辑 textarea
+- 不再展示“请先上传参考图生成预览”之类的说明文案
+- 未生成前允许为空，但界面仍保留固定编辑区域
+- 建议最小高度约 `260px ~ 320px`
+- 加载中只显示轻量状态提示，不挤压编辑区高度
+
+### 提取到的变量
+
+作为结果工作区的一部分展示，而不是附属信息。
+
+规则：
+
+- 变量名只读
+- 变量值可编辑
+- 区域需具备明确最小高度和滚动能力
+- 变量行之间保持稳定间距，避免像表单碎片一样堆在底部
+
+## 变量策略
+
+### 产品规则
+
+- 变量只在首次生成预览时自动提取一次
+- 用户编辑 prompt 后，不自动重算变量
+- 不再提供“同步变量”或“重新提取变量”按钮
+- 点击应用时：
+ - 直接采用当前 prompt 文本
+ - 直接采用当前变量区值
+ - 不再做额外重算
+
+这意味着 prompt 与变量允许短暂不完全一致，这是有意的简化，不视为缺陷。
+
+### 数量上限
+
+变量总数必须控制在 5 个以内。
+
+采用三层约束：
+
+1. 参考图生成与迁移模板中，要求输出更适合少量高价值变量抽取的结构
+2. 变量提取模板中明确要求最多返回 5 个变量，并按重要性排序
+3. UI 服务层增加硬上限兜底，只保留前 5 个变量
+
+### 优先级
+
+优先保留以下变量类型：
+
+- 主体
+- 数量
+- 颜色
+- 关键动作
+- 关键场景或核心风格锚点
+
+低优先级项应避免被抽成变量：
+
+- 细碎修饰词
+- 重复限定词
+- 对最终复用价值不高的局部装饰
+
+## 状态与数据流
+
+### 打开弹窗
+
+1. 读取当前原始提示词
+2. 若非空，生成摘要用于“检测到当前提示词”
+3. 初始化模式：
+ - 有当前提示词时默认 `风格迁移`
+ - 无当前提示词时默认 `复刻图片`
+4. 清空本次参考图预览结果
+
+### 上传参考图后生成预览
+
+#### 复刻图片
+
+1. `extractReferenceSpecFromImage`
+2. `composePromptFromReferenceSpec`
+3. `extractPromptVariables`
+4. 将结果填入弹窗中的 prompt 和变量区
+
+#### 风格迁移
+
+1. `extractReferenceSpecFromImage`
+2. `migratePromptWithReferenceSpec`
+3. `extractPromptVariables`
+4. 将结果填入弹窗中的 prompt 和变量区
+
+### 应用到当前提示词
+
+1. 使用当前编辑框中的 prompt 作为最终文本
+2. 使用当前变量区中的值覆盖当前临时变量
+3. 关闭弹窗
+4. 不再保留撤销快照
+
+## 需要删除的复杂度
+
+### 删除撤销链路
+
+移除以下能力：
+
+- 弹窗应用后的撤销提示条
+- `lastApplySnapshot`
+- `canUndoLastApply`
+- `undoLastApply()`
+- 相关 UI 按钮与成功提示
+
+原因：
+
+- 弹窗本身已承担最终确认职责
+- 应用后撤销会引入额外状态与心智负担
+- 不符合本功能“确认后替换”的简单模型
+
+### 删除变量同步链路
+
+移除或保持不存在以下能力：
+
+- 手动同步变量
+- 自动重算变量
+- prompt 变更后的失焦刷新
+- 变量与 prompt 的双向联动逻辑
+
+原因：
+
+- 这会把弹窗变成编辑器，不再是前置参考改造工具
+- 当前 MVP 的价值在于快速得到一份可用起点，而不是维护强一致的数据模型
+
+## 文案调整
+
+### 主要文案
+
+- `识图提取` 保持为 `参考图`
+- `检测到当前提示词：{prompt}` 改为分离式标题和摘要内容，不再拼成一整句
+- `保留当前内容` 改为 `风格迁移`
+- `按参考图生成` 改为 `复刻图片`
+
+### 模式说明
+
+- `风格迁移`：在原提示词的基础上学习图片风格进行改造
+- `复刻图片`：丢弃原始提示词内容，反推图片对应提示词
+
+## 影响范围
+
+### UI
+
+- `packages/ui/src/components/image-mode/ImageText2ImageWorkspace.vue`
+- `packages/ui/src/composables/image/useReferencePromptDialog.ts`
+- `packages/ui/src/i18n/locales/zh-CN.ts`
+- `packages/ui/src/i18n/locales/zh-TW.ts`
+- `packages/ui/src/i18n/locales/en-US.ts`
+
+### 服务与模板
+
+- `packages/ui/src/services/ImageStyleExtractor.ts`
+- `packages/core/src/services/template/default-templates/image-prompt-composition/`
+- `packages/core/src/services/template/default-templates/image-prompt-migration/`
+- `packages/core/src/services/template/default-templates/variable-extraction/`
+
+## 错误处理
+
+- 上传失败时，维持当前 prompt 和变量不变
+- 参考图解析失败时，仅提示本次生成失败，不关闭弹窗
+- 变量提取失败时，允许 prompt 继续展示，但变量区为空
+- 当前提示词为空时，不展示模式选择，也不报错
+
+## 测试要点
+
+### 交互测试
+
+- 弹窗不再显示应用后撤销提示
+- 当前提示词非空时，先显示摘要，再显示模式选择
+- 模式名称和说明文案已切换为 `风格迁移 / 复刻图片`
+- 参考图区域使用缩略图，不再占用大图高度
+- prompt 区和变量区有稳定高度
+
+### 逻辑测试
+
+- `风格迁移` 默认选中，仅在当前提示词非空时出现
+- `复刻图片` 在当前提示词为空时自动生效
+- 应用时不再保存撤销快照
+- 编辑 prompt 不触发变量自动刷新
+- 变量数量始终不超过 5 个
+
+### 回归测试
+
+- 未使用参考图时，文生图现有流程不变
+- 图生图工作区不受影响
+- 三段式内部服务链路保持不变
+
+## 验收标准
+
+- 用户能在首次打开弹窗时看懂“当前看到了什么”和“可以怎么用这张图”
+- 参考图不再抢占主编辑区空间
+- `风格迁移 / 复刻图片` 的语义差异无需额外解释即可理解
+- 弹窗应用链路不再包含撤销和同步变量等补救型复杂度
+- 变量数量被稳定控制在 5 个以内
+
+## 实施建议
+
+建议按以下顺序实施：
+
+1. 先删状态复杂度
+ - 移除撤销状态与相关文案
+2. 再改 UI 信息架构
+ - 缩略图参考图
+ - 当前提示词摘要卡
+ - 模式卡
+ - 底部混合布局
+3. 最后收变量策略
+ - 提取模板收紧
+ - 服务层硬上限兜底
+
+这样可以先把交互心智收干净，再保证变量结果稳定。
