Fixed #32018 -- Extracted admin colors into CSS variables.
Defined all colors used in the admin CSS as variables. Implemented the
following standardizations and accessibility improvements while at it:

- Improved the contrast of text to not use ratios of less than 3:1 anymore.
- Most hover states already used desaturated and darkened colors.
  Changed object tools to follow the same rule instead of showing the
  primary color on hover.

Various places used similar colors; those have been merged with the goal
of reducing the count of CSS variables. Contrasts have been improved in
a few places.

- Many borders used slightly different colors (e.g. #eaeaea vs. #eee)
- Help texts used #999, this has been changed to --body-quiet-color
  (#666) which has a better contrast.

Introduced fast color transitions on links and buttons.

The documentation in this tree is in plain text files and can be viewed using any text file viewer.

It uses ReST (reStructuredText), and the Sphinx documentation system. This allows it to be built into other forms for easier viewing and browsing.

To create an HTML version of the docs:

  • Install Sphinx (using python -m pip install Sphinx or some other method).
  • In this docs/ directory, type make html (or make.bat html on Windows) at a shell prompt.

The documentation in _build/html/index.html can then be viewed in a web browser.
