A CLI wrapper for Gemini's image generation that actually handles the annoying parts: green screen workflows for transparent assets, multi-reference style transfer, exact dimension control, and built-in cost tracking. Default model is Flash (cheap and fast at ~$0.067 per 1K image), but you can bump to Pro when quality matters. The transparent asset workflow is clever: it auto-prompts for green screen generation then uses FFmpeg to key it out cleanly. Supports everything from 512px sketches to 4K renders with standard aspect ratios. If you're mocking up UI, generating game sprites, or need quick marketing visuals without opening Photoshop, this is the kind of tool that just gets out of your way.
