Fast Note Sync Service architecture prompt

Create a restrained 16:9 technical architecture diagram for Fast Note Sync Service. On the left, show Obsidian desktop and mobile clients, a browser management interface, automation scripts, and an AI/MCP client. In the center, show one Fast Note Sync Service boundary with three labeled entries: WebSocket sync, HTTP/REST, and MCP. Inside the boundary, show note, folder, attachment, history, user, token, backup, and Git sync responsibilities without inventing source-level dependencies. On the right, show SQLite/MySQL/PostgreSQL for metadata and local filesystem/S3/R2/OSS/MinIO/WebDAV for files and backups. Use a light background, neutral colors with restrained green and blue accents, high contrast Chinese labels, no copied logos, no product screenshots, and no decorative gradients. This remains prompt-only until the user explicitly requests image generation.
