CloudFlare-ImgBed architecture prompt

Create a restrained 16:9 technical architecture diagram on a light background for CloudFlare-ImgBed v2.7.6. Show three clearly separated layers from left to right: upload and access clients (browser, REST API, WebDAV client); the CloudFlare-ImgBed management layer (frontend, Hono/Functions routes, authentication, file metadata and channel selection); persistence backends (Cloudflare D1 or KV for metadata, Docker SQLite for metadata, Cloudflare R2, S3-compatible storage, Telegram, Discord, Hugging Face, external WebDAV and Docker local object storage for file bytes). Make the split between metadata and actual file bytes visually unmistakable. Use concise Chinese labels, straight connectors, high contrast and a professional infrastructure-documentation style. Do not invent product screens, performance numbers, provider relationships or copied third-party logos. This remains prompt-only until image generation is explicitly authorized.
