• The badge:
• The badge is created following how Ruff defines its logo, as described in https://github.com/python-poetry/poetry/issues/7270#issuecomment-1476106589.
• The message background color was extracted from the logo to match it.
• The logoSvg was taken directly from the official Poetry website repo: https://github.com/python-poetry/website/blob/main/static/images/logo-origami.svg

@johnthagen I was thinking something like: https://hatch.pypa.io/latest/next-steps/#community. Please add a "community" page in docs describing the usage of the badge, with a JSON file hosted statically in this repo.
