Sphinx Favicon

Sphinx Favicon is an active Sphinx extension, currently at version 1.1.0, that enhances the ability to add custom favicons to Sphinx HTML documentation. It allows users to define favicons directly in `conf.py` with various attributes like `rel`, `sizes`, `href`, or `name`, providing more flexibility than Sphinx's default `favicon.ico` support. The library maintains a steady release cadence with recent updates focusing on bug fixes and dependency modernization.
