+# AI Image Generator Flow
+
+## Setup
+
+1.  **Install Dependencies**:
+    ```bash
+    npm install
+    ```
+
+2.  **Environment Variables**:
+    A `.env` file has been created. Ensure the following keys are correct:
+    *   `R2_ACCOUNT_ID`: Your Cloudflare Account ID.
+    *   `R2_ACCESS_KEY_ID`: Your R2 Access Key ID.
+    *   `R2_SECRET_ACCESS_KEY`: Your R2 Secret Access Key.
+    *   `R2_BUCKET_NAME`: The name of your R2 bucket (Default: `ai-flow`).
+    *   `API_KEY`: Your Wuyin Keji API Key.
+
+3.  **Run Server**:
+    ```bash
+    node server.js
+    ```
+    Access at `http://localhost:3000`.
+
+## Features
+
+1.  **Upload**: Uploads reference images to Cloudflare R2.
+2.  **Prompt Generation**: Uses LLM to generate prompts based on `prompt.md` template.
+3.  **Image Generation**: Uses NanoBanana to generate images from prompts.
+4.  **History**: Saves generated images and prompts locally.
+5.  **Batch Download**: Download all generated images.
+
+## Notes
+*   Ensure your R2 bucket allows public access or configure a custom domain in `.env` as `R2_PUBLIC_DOMAIN`.
+*   The application saves state to browser `localStorage` to prevent data loss on refresh.

+# Role: 亚马逊高级电商视觉总监 & AI提示词工程师
+# Objective: 根据提供的产品信息和图片需求，编写适用于AI绘画工具（如NanoBanana/Midjourney/Stable Diffusion）的高质量英文提示词（Prompts）。
+
+# Guidelines for Prompt Generation (视觉转化规则):
+1. **结构化写作**: 每个Prompt必须包含：[主体描述] + [环境/背景] + [光影/氛围] + [构图视角] + [画质修饰词]。
+2. **卖点视觉化**: 不要直接在Prompt里写卖点文字（如"Waterproof"），而是描述表现该卖点的画面（如"Water droplets beading off the surface, hydrophobic effect"）。
+3. **一致性控制**: 
+   - 确保所有图片中的产品必须是参考图中的产品。
+   - 主图（Main Images）通常需要纯白背景（White Background）或极简背景。
+   - A+图（Lifestyle Images）需要具体的居家或户外场景，具有生活感。
+4. **尺寸适配**: 
+   - 主图 Prompt 末尾添加参数 `--ar 1:1`
+   - A+图 Prompt 末尾添加参数 `--ar 3:2` (或接近970:600的比例)
+
+# Output Format (JSON):

+```text
+[IMAGE EDITING TASK - NOT GENERATION]
+
+REFERENCE IMAGE ANALYSIS:
+The reference image shows: An ice-blue TOUCHDOG soft pet recovery cone collar in flat lay position. 
+CRITICAL SHAPE DETAIL: The product has a C-SHAPED OPENING (not a closed circle) - there is a GAP on the left side where the velcro strap attaches. This opening allows the collar to wrap around the pet's neck.

+4. TOUCHDOG brand text on the product
+5. Green/teal inner rim around the neck hole

+         S | 7.2-8.4IN | 4IN
+         M | 8.8-10.4IN | 5IN
+         L | 10.8-12.4IN | 6IN
+         XL | 12.8-14.4IN | 7IN
+5. Add note in coral: "ALWAYS MEASURE YOUR PET'S NECK BEFORE SELECTING A SIZE"
+6. Add subtle paw print watermarks
+
+LAYOUT SPECIFICATION:
+      - Left 45%: Product image maintaining C-shape opening
+      - Right 55%: Size chart table
+      - Top: Title
+      - Bottom: Note text
+
+STYLE GUIDE:
+Clean infographic style. The product's C-shaped opening must be clearly visible - this is a key feature showing how it wraps around the neck.
+
+OUTPUT: 3:2 landscape ratio, professional Amazon listing quality
+
+FINAL CHECK: Before output, verify that the pet and product in the result match the reference image EXACTLY in:
+- Species, breed, fur color and pattern
