Generate images via Google Gemini's "nano banana" model (Gemini 2.5/3 Flash Image) by driving gemini.google.com in Chrome via the chrome-devtools MCP, then save and display the result inline. Use this skill whenever the user wants to create, generate, make, draw, or render an image, picture, illustration, poster, icon, logo, or any visual artwork — even if they don't mention Gemini by name. Also use when the user provides a short visual description and clearly expects an image back. Default save path is $TMPDIR.
