@AthanasEdigerMartin ⚠️ CI hint: Build and lint checks are failing.
🔍 Check that all imports in cli.py are used and consistent with ruff formatting. Running ruff check paperbanana/ locally usually points out exactly which lines need attention.
💡 Tip: PaperBanana prefers fully cleaned and formatted scripts before merging — think of this as making your CLI “reference-quality” like a methodology diagram.
