Run a saved FLORA technique — a multi-step visual workflow such as background swap, relighting, upscale, model swap, or sketch-to-render. Use when the user names a technique, asks to transform an image they already have ("put this on a clean background", "match this lighting", "upscale this", "make this look photographed"), or asks what FLORA can do. Do not use for a plain text-to-image request with no source image, and do not use to inspect existing project work.
