Notes:
google/nano-banana-pro (Nano Banana Pro). If it fails and default is used, script falls back to black-forest-labs/flux-1.1-pro.16:9 (header-friendly); override via --aspect-ratio.2K; override via --resolution.direct (multipart upload to /media/upload). Use --upload-mode import to import from a URL or --upload-mode skip to stop after generating the image.~/scripts/.venv/bin/python if available; otherwise it falls back to python3.Commit current local changes to a new feature branch, push it to origin, and use the gh CLI to open a pull request back into the current branch or a user-specified base branch. Use when the user wants a gh-commit-and-push style workflow that avoids committing directly to the base branch and creates a PR instead.
