Minimal, security-conscious MCP server for Google Gemini image generation. Defaults to **Nano Banana 2 / Gemini 3.1 Flash Image** (`gemini-3.1-flash-image-preview`) and **1024px WebP output** so day-to-day agent usage does not accidentally produce Pro-tier, 2K, or 4K image bills. Output is automatically resized + re-encoded to web/email/mobile-friendly
