Sphinx Immaterial Theme

Sphinx-Immaterial is an adaptation of the popular mkdocs-material theme for the Sphinx documentation system. It is actively maintained to stay up to date with the upstream mkdocs-material repository, incorporating HTML templates, JavaScript, and styles with mostly minor modifications. The current version is 0.13.9, with frequent minor releases as seen in the GitHub changelog, often driven by upstream `mkdocs-material` updates or Sphinx compatibility fixes.
