Dear website, documentation and design teams,

Several documentation manuals are being generated now using 
ReStructuredText and Sphinx, and it would be nice that a Debian theme in 
Sphinx is created and used to match our docs appearance with the Debian 
website colours etc.

Currently in the website we publish, at least:

* Debian Policy: https://www.debian.org/doc/debian-policy/
* Debian Developers Reference: 
https://www.debian.org/doc/manuals/developers-reference/index.en.html
* Testing Release notes: currently in 
https://www.debian.org/releases/testing/release-notes/ but that may change

The upstream documentation about theming is here:
  http://www.sphinx-doc.org/en/stable/theming.html

Please take into account that currently the machine www-master where the 
website is built runs bullseye (sphinx version: 3.4.3-2, but at some 
time it will be upgraded to bookworm (sphinx version: 5.3.0-4).

Kind regards
