+# 豆维 · 可扫码的拼豆
+
+输入一句话（可以再选一张照片），生成**用微信扫一扫就能读出内容**的 MARD 拼豆图纸，并支持导出 PDF 或图片。
+
+## 本版重点
+
+- **一眼看懂**：首屏直接说明用途，页面按“写一句话 → 选张照片 → 导出图纸”三步走，打开就能看到示例效果。
+- **更快**：配色查表加速，色格数据不再走页面数据通道；PDF 改为矢量直出（毫秒级，文件更小）；导出时不再重复绘制。
+- **更好看、更好扫**：
+ - 感知更准的配色（OKLab）
+ - 照片按面积取平均色，不再有锯齿
+ - 相邻色块自动平滑，零散颜色自动合并，所需豆子种类更少
+ - 二维码定位图形强制高对比
+ - 本机扫码自检：扫不出时一键优化
+- **打印友好**：PDF 为 A4 矢量图纸，大作品会自动分块并附总览页；每一格都印有色号，另附带用量的清单。
+- **精选色板**：除标准 221 色和完整 291 色外，还提供 144/96/72/48/24 色精选套装，方便少买豆。
+
+## 内容安全链路（按微信平台要求）
+
+| 环节 | 措施 |
+| --- | --- |
+| 二维码文字、扫码导入的文字、水印 | 云函数调用 `security.msgSecCheck` v2（带 openid、按场景值检测），结果为 risky 或 review 均拦截 |
+| 照片 | 选图后立即压缩到官方推荐的 750×1334 以内，由云函数调用 `security.imgSecCheck`；**检测通过前不能应用照片** |
+| 检测异常 | 一律视为未通过，不允许生成与导出（fail-closed） |
+| 导出前 | 再次校验全部文本（已通过的走缓存，不增加等待） |
+| 云函数加固 | 必须有 OPENID；只接受 `sec-check/` 目录下的 jpg；通过文件头判断格式；限制 1MB；检测后立即删除云端临时文件 |
+| 隐私 | 已开启 `__usePrivacyCheck__`，内置隐私授权弹窗；页脚设有“隐私保护指引”入口 |
+| 投诉与反馈 | 页脚提供“内容规范”说明及 `open-type="feedback"` 的投诉反馈入口 |
+| 分享 | 分享出去的只是小程序卡片，不带用户内容 |
+
+## 部署步骤
+
+1. 用微信开发者工具打开本目录（appid 已配置）。
+2. 右键 `cloudfunctions/quickstartFunctions` →「上传并部署：云端安装依赖」。**本版云函数有改动，必须重新部署。**
+3. 在云开发控制台 → 存储中确认可以写入 `sec-check/` 目录（默认权限即可）。
+4. 在小程序管理后台 →「设置 → 服务内容声明 → 用户隐私保护指引」中声明：选择图片/拍照（`chooseMedia`）、保存到相册（`saveImageToPhotosAlbum`）、扫码（`scanCode`）。
+5. 真机测试：正常/违规文字、正常/违规图片、断网时的检测异常，确认都会被正确拦截和提示。
+
+## 说明
+
+- 为保证扫码成功率，**二维码默认保留 1 格白边**。如需原来的“无白边”效果，可在「高级设置 → 白边」中选择“无”。
+- 圆豆、中空豆样式只影响图纸的显示效果，实际拼出来的位置与方豆完全一致。
+- 第三方代码：`utils/qrcore`（node-qrcode，MIT）、`utils/vendor/jsqr.js`（jsQR，Apache-2.0）。
+
+## 首屏演示动画 & 宣传视频
+
+- 首次打开（还没写内容）时，预览区播放 12 秒 1:1 演示动画：写一句话 → 编成二维码 → 融进照片 → 微信一扫 → 结尾卡片。
+- 动画由 `miniprogram/utils/intro.js` 纯代码实时绘制，**不含任何视频/图片素材，几乎不占包体积**（约 20KB）。演示作品由真实配色引擎生成，画面里的二维码真的能扫出 “Happy Birthday!”。
+- 滑出屏幕、切到后台、打开裁剪时自动暂停；点一下预览区重新播放；写下内容（或选了照片）后自动切回真实二维码。
+- `docs/promo/` 里是用同一套代码渲染的宣传视频（1080 / 720，含原创合成配乐）和封面图，可直接发公众号。该目录不在 `miniprogram/` 内，不计入小程序包体积。

+# 豆维 · 视频文案与分镜脚本
+
+> 目标：用一个短视频介绍「豆维 · 可扫码的拼豆」小程序，让观众理解它是什么、为什么有趣、怎么做出来。
+> 结构：提出想法 → 实现想法 → 制作例子 → 完成例子。
+
+---
+
+## 一、视频定位与调性
+
+| 维度 | 建议 |
+|------|------|
+| 时长 | 主版本 60–90 秒（B站 / 朋友圈 / 公众号），另附 15–30 秒短视频版 |
+| 调性 | 温暖手作 × 科技惊喜，不是冷冰冰的产品演示 |
+| 核心情绪 | 「拼豆不止是一幅画，它是一封能被读到的信」 |
+| 目标观众 | 拼豆爱好者、手工创作者、喜欢送独特礼物的人 |
+| 画面风格 | 暖色调，木桌面，自然光；手机屏幕录制与实物特写交替出现 |
+
+---
+
+## 二、核心文案（Slogan / 一句话介绍）
+
+以下任选一条作为标题或结尾定版字：
+
+1. **豆维 · 可扫码的拼豆**
+2. **每一颗珠子，都藏着一句话。**
+3. **拼出来的二维码，扫出来的心意。**
+4. **把想说的话，拼进一幅画里。**
+5. **看得见，也读得到。**
+
+推荐主标题：**看得见，也读得到。——豆维，可扫码的拼豆**
+
+---
+
+## 三、主版本分镜脚本（60–90 秒）
+
+> 旁白以第一人称「我」叙述，语气像朋友分享，不念广告稿。
+> 「画面」列标注了你需要准备的素材类型；如果你已有类似镜头，直接对应即可。
+
+| 幕 | 时间 | 画面 | 旁白 / 字幕 | 剪辑提示 |
+|----|------|------|-------------|----------|
+| **第一幕：提出想法** | 0:00–0:08 | 桌面上摆着几幅拼豆作品，阳光照进来。手拿起其中一幅，翻到背面，又翻回来。 | **旁白：** 我做了很多拼豆作品，挂在墙上很好看。但我总在想——它能不能，不止是一幅画？ | 慢推镜头，配温暖的钢琴或指弹吉他。最后一帧画面停在作品特写。 |
+| | 0:08–0:14 | 手拿起手机对准拼豆作品「扫一扫」——屏幕弹出一条消息或链接。 | **旁白：** 能不能扫一下，就能看到我想说的话？ | 这是全片第一处「惊喜时刻」，音效清脆，屏幕内容要清晰可见。 |
+| **第二幕：实现想法** | 0:14–0:24 | 切到手机屏幕录屏：打开豆维小程序，输入一段文字。 | **旁白：** 所以我做了「豆维」——一个可扫码的拼豆图纸生成器。输入一段话，或者一个链接。 | 屏幕录制加速 2–3 倍，打字过程快放。 |
+| | 0:24–0:34 | 录屏：导入一张照片，裁切、去背景。 | **旁白：** 再选一张你喜欢的照片。它会把照片和二维码，合成一幅完整的拼豆图纸。 | 展示裁切弹窗操作，去背景效果前后对比。 |
+| | 0:34–0:44 | 录屏：拖动滑块调整二维码大小和位置，切换「丰富 / 平衡 / 稳定」模式。 | **旁白：** 二维码可以放大缩小、移到任何位置。颜色会自动匹配 221 色的拼豆色库，还能选择更注重美观、还是更保证能扫出来。 | 滑块操作用慢动作展示，让观众看到图案实时变化。 |
+| **第三幕：制作例子** | 0:44–0:52 | 导出的图纸打印出来，摆在桌上。开始一颗一颗摆珠子。 | **旁白：** 图纸保存下来，打印出来，就可以开始拼了。 | 延时摄影或快剪，展示摆珠过程，保留几秒真实速度的特写。 |
+| | 0:52–0:58 | 熨斗烫过，拼豆板冷却，掀开，成品完成。 | **旁白：** 熨好，冷却，掀开—— | 掀开那一刻音效「叮」，画面干净利落。 |
+| **第四幕：完成例子** | 0:58–1:10 | 手持成品对镜头展示，然后用手机扫描。屏幕上弹出一开始输入的那段话。 | **旁白：** 它不只是一幅画。你把手机对准它——就能读到里面藏着的话。 | 这是全片情绪最高点。扫描过程用真实速度，屏幕内容要清楚。 |
+| | 1:10–1:20 | 多个成品排列展示（不同图案、不同颜色），最后画面淡出到品牌 Logo 和小程序码。 | **旁白：** 豆维，可扫码的拼豆。看得见，也读得到。 | 结尾定格 3 秒，放小程序码，方便观众扫码体验。 |
+
+---
+
+## 四、15 秒短视频版（抖音 / 视频号快闪）
+
+| 时间 | 画面 | 字幕（无旁白，纯字幕流） |
+|------|------|--------------------------|
+| 0–3s | 手拿起拼豆作品 → 手机扫描 → 屏幕弹出消息 | 拼豆里，藏着一条消息 |
+| 3–8s | 快剪：输入文字 → 导入照片 → 图纸生成 → 摆珠 | 豆维：输入一句话，选一张图，生成拼豆图纸 |
+| 8–13s | 熨烫 → 掀开 → 成品再扫一次 | 拼好，烫平，扫一下—— |
+| 13–15s | 品牌 Logo + 小程序码 | 消息就出来了。豆维 · 可扫码的拼豆 |
+
+> 快闪版不需要旁白，靠音乐节奏 + 字幕推进。音乐选节奏感强的电子或 Lo-Fi。
+
+---
+
+## 五、30 秒版本（朋友圈 / 公众号内嵌）
+
+节奏比 15 秒版稍慢，保留 4 个关键节点：
+
+1. **悬念**（5s）：拿起作品 → 扫码 → 弹出内容
+2. **怎么做**（10s）：小程序操作快剪（输入 → 导图 → 调整 → 导出）
+3. **手作过程**（8s）：摆珠延时 + 熨烫 + 掀开
+4. **结尾**（7s）：成品特写 + 再扫一次 + 定版
+
+配乐：轻快指弹吉他或 Lo-Fi，音量压低，让旁白清晰。
+
+---
+
+## 六、素材清单
+
+拍摄前对照这份清单，确认已拍到以下镜头（√ 为已有，× 为待补）：
+
+| 素材 | 用途 | 状态 |
+|------|------|------|
+| 多幅完成的拼豆作品摆拍（正面 / 斜角 / 背面） | 开头悬念、结尾展示 | ☐ |
+| 手机扫描拼豆作品并弹出内容的实拍 | 全片核心「惊喜时刻」，需拍 2–3 次 | ☐ |
+| 豆维小程序屏幕录制：输入文字、导入图片、裁切、调 QR 位置、切模式 | 第二幕 | ☐ |
+| 图纸导出 / 打印的镜头 | 第三幕开头 | ☐ |
+| 摆珠延时或快剪素材 | 第三幕 | ☐ |
+| 熨斗烫拼豆 + 掀开的特写 | 第三幕高潮 | ☐ |
+| 成品多角度特写（自然光 / 桌面） | 结尾 | ☐ |
+
+---
+
+## 七、剪辑建议
+
+- **转场**：幕与幕之间用干净的硬切或快速模糊，不要花哨转场。产品视频要显得克制。
+- **音乐**：主版本选温暖的原声吉他或钢琴；快闪版选节奏感强的 Lo-Fi / 电子。全片一首歌，不要中途换。
+- **节奏**：第三幕（摆珠）可以稍慢，让观众感受手作质感；第二幕（录屏）加速推进。
+- **字幕**：全程加简体中文字幕，关键词用品牌色 `#416d62`（深绿）高亮。
+- **结尾**：小程序码至少停留 3 秒，让观众来得及扫码。
+
+---
+
+## 八、旁白全文（主版本，可直接朗读）
+
+> 我做了很多拼豆作品，挂在墙上很好看。但我总在想——它能不能，不止是一幅画？能不能扫一下，就能看到我想说的话？
+>
+> 所以我做了「豆维」。输入一段话，或者一个链接，再选一张你喜欢的照片。它会把照片和二维码，合成一幅完整的拼豆图纸。二维码可以放大缩小、移到任何位置，颜色会自动匹配 221 色的拼豆色库，还能选择更注重美观、还是更保证能扫出来。
+>
+> 图纸保存下来，打印出来，就可以开始拼了。熨好，冷却，掀开——
+>
+> 它不只是一幅画。你把手机对准它，就能读到里面藏着的话。
+>
+> 豆维，可扫码的拼豆。看得见，也读得到。

+# 审核驳回处理：深度合成误判 — 文案与步骤
+
+> 驳回原因（2026-09-30）：小程序服务内容涉及深度合成技术（如 AI 问答、AI 换脸视频、AI 绘画等），属个人主体尚未开放服务类目，建议申请企业主体类型小程序。
+
+## 结论
+
+代码里没有任何 AI 功能：文字是标准二维码编码；"照片转图纸"是确定性本地图像处理（按网格取平均色 → 映射到 221 种固定色号），不用任何模型、不生成新图像。被判"深度合成"大概率是**后台简介 / 服务类目 / 服务内容声明的表述**或审核员看到"照片→生成图纸"产生的误判。
+
+## 路径 A（推荐，最快）：修正表述后重新提审
+
+### 1. 检查后台三处（mp.weixin.qq.com）
+
+| 位置 | 检查项 |
+| --- | --- |
+| 服务类目 | 改为 **工具 - 图片处理**（个人主体可选）；删除任何 AI / 深度合成相关类目 |
+| 服务内容声明 / 提审问卷 | 凡问"是否提供 AI 生成内容、AI 问答、AI 绘画、深度合成"一律选 **否** |
+| 小程序简介 | 换成下方"新简介"，去掉"生成器 / 一键生成 / 智能"等字眼 |
+
+### 2. 新简介（约 90 字，上限 120）
+
+```
+手工拼豆图纸工具：输入一句话或选一张照片，按 MARD 标准色号排成拼豆图纸，拼好微信一扫就能读出内容。支持 A4 矢量 PDF 与图片导出、用量清单。照片仅在本地做取色处理，并经微信内容安全检测。
+```
+
+### 3. 版本描述 / 审核备注（重新提审时填写）
+
+```
+本小程序为拼豆手工图纸工具，不使用任何人工智能或深度合成技术，无 AIGC 功能：
+1. "照片转图纸"为确定性本地图像处理：将用户上传照片按网格取平均色，再映射到固定的 221 种拼豆标准色号（色彩量化 + 最近邻查表），不生成、不合成任何新图像内容，不涉及人脸或生物特征编辑；
+2. 文字功能是将文本编码为标准二维码点阵，非内容生成；
+3. 所有处理均在用户手机本地完成，且已接入微信内容安全接口（security.msgSecCheck / imgSecCheck），检测未通过时禁止生成与导出（fail-closed）。
+请按"工具-图片处理"类目审核。
+```
+
+## 路径 B：申诉
+
+若不想改简介，可直接对本次审核结果发起申诉（审核结果页 → 申诉），粘贴下文：
+
+```
+本小程序为拼豆手工图纸工具，不涉及深度合成技术：
+(1) 不使用 AI 模型 / 神经网络，无 AI 问答、AI 绘画、AI 换脸等 AIGC 功能；
+(2) 照片功能仅做确定性色彩量化：按网格取平均色并映射到 221 种固定标准色号，属于常规图像处理，不生成新图像、不做人脸或生物特征编辑；
+(3) 文字功能为标准二维码编码；
+(4) 已接入微信内容安全检测（msgSecCheck / imgSecCheck），检测未通过不能生成或导出。
+恳请复核，建议按"工具-图片处理"类目审核。
+```
+
+申诉未通过时：修改简介与类目后按路径 A 重新提审（改了表述基本都能过）。
+
+## 路径 C：仅当二次被拒或想保留"生成"叙事
+
+1. **隐藏照片功能**（只保留文字 → 二维码图纸，纯编码无争议）——我可以直接改代码；
+2. **升级主体**：注册个体工商户 / 企业 → 主体变更 → 申请深度合成相关类目 + 算法备案。仅在以后真要做 AI 功能时才值得，当前工具用不到。
+
+## 顺手可做的降风险小改动（可选）
