'What it looks like' section right under the intro: a clean full-workspace hero shot plus Composer and Engine Settings side by side, generated from the mocked tour demo (no ComfyUI/GPU needed) by a new tools/showcase/capture_clean.mjs (npm run capture:clean) - same scaffolding as capture.mjs but with the tour overlay stripped, so shots are undimmed and card-free.
