+# 饮食偏好调研页面重新设计 实现计划
+
+> **面向 AI 代理的工作者:** 必需子技能:使用 superpowers:subagent-driven-development(推荐)或 superpowers:executing-plans 逐任务实现此计划。步骤使用复选框(`- [ ]`)语法来跟踪进度。
+
+**目标:** 将 `cfc-frontend/pages/diet/preferences.vue` 从 3 张灰色长表单卡改造为 3 步引导式问卷(Step1 忌口必填 / Step2 口味偏好 / Step3 健康目标),对齐「暖灶」暖橙主题,补全 `mustEat`/`cookingMethods` 采集。
+
+**架构:** 单 `.vue` 文件内维护 `currentStep`(1/2/3)+ 顶部进度条 + 底部"上一步/下一步/完成";数据用扁平数组字段存储(`allergies`/`absoluteAvoid`/`flavorPref`/`cuisinePref`/`cookingMethods`/`healthGoals`/`mustEat`),chip 选中态用 `arr.indexOf(name) >= 0` 内联表达式;`onLoad` 预填、`saveDietPreferences` 一次性提交。
+
+**技术栈:** uni-app Vue 2 Options API(微信小程序),flexbox(禁 Grid),无 `?.`,`:key`/`:class` 禁方法调用式绑定。
+
+**规格文档:** `docs/superpowers/specs/2026-08-30-diet-preferences-redesign-design.md`
+
+---
+
+## 文件结构
+
+| 文件 | 职责 | 变更 |
+|------|------|------|
+| `cfc-frontend/pages/diet/preferences.vue` | 3 步引导问卷(模板 + 逻辑 + 样式) | 重写 |
+| `cfc-frontend/pages.json` | 页面注册与标题 | 不变(已注册,标题"饮食偏好调研") |
+| `cfc-frontend/utils/api.js` | `getDietPreferences`/`saveDietPreferences` | 不变(已存在) |
+| `cfc-backend/**` | 数据存储 | 不变(`must_eat`/`cooking_methods` 列已存在) |
+
+---
+
+## 任务 1:重写 preferences.vue — 模板结构(数据层 + 进度条 + Step1)
+
+**文件:**
+- 修改:`cfc-frontend/pages/diet/preferences.vue`(整体重写,保留现有 `savePreferences` 校验语义)
+
+- [ ] **步骤 1:重写 `<script>` data 与状态字段**
+
+将整个文件替换为以下结构(模板与样式在任务 2、3 中填充,先确保逻辑完整):
+
+```vue
+<script>

+
+**验证:** 无 CSS Grid、无中文类名、无 `?.`。
+
+- [ ] **步骤 2:验收检查**
+
+对照规格验收清单逐条核验:
+- [ ] Step1 必填校验(`allergies.length === 0 && absoluteAvoid.length ===0` 时 goNext 弹 toast)
+- [ ] Step2 四项 chip 均可选
+- [ ] Step3 必吃/目标 chip 可选,无"系统推荐目标"区块
+- [ ] 预填回填(`loadPreferences` 各数组赋值)
+- [ ] 提交含 `cookingMethods`/`mustEat`(空数组也可)
+- [ ] 暖橙主题(背景渐变/`#FF8C42`/圆角阴影)
+- [ ] 无 `?.`、无 Grid、`:key`简单表达式、无自定义 nav-title
+
+- [ ] **步骤 3:Commit**
+
+```bash

+git commit -m "style(diet): 饮食偏好调研 暖灶暖橙主题样式"

+
+## 自检记录
+
+**1. 规格覆盖度:** 规格 4 节全覆盖——步骤流(任务1 进度条+底栏/任务2 内容)、交互(chip+自定义)、视觉(任务3)、后端兼容(零改动,全部字段映射见任务1 save 提交体)。
+**2. 占位符扫描:** 无"待定/TODO"。任务2 步骤1 已含 Step2 四卡片完整代码(辣度/口味/菜系/烹饪方式),无"类似任务"式简写。
+**3. 类型一致性:** 字段名 `allergies/absoluteAvoid/religiousDiet/spiceLevel/flavorPref/cuisinePref/cookingMethods/healthGoals/mustEat` 与 DTO 一致;方法 `toggleChip/openCustom/addCustom/goNext/goPrev/savePreferences` 前后引用一致;预设常量名 `presetAllergies...presetGoals` 与 computed 一致。
+
+**已知修正(对比规格):** Step3 无"系统推荐目标"区块(规格自检已确认后端无 `systemGoals` 数据源)。
+
+---
+
+**验证方式:** 修改后需在 HBuilderX 重新打包(agent 不执行 build 命令);`node --check` 校验 script 块语法。
