== Background
The `color-base` token needs a `-fixed` equivalent. On wiki it is quite common for dark mode, where elements have white backgrounds to need to now define color to ensure the content works in dark mode. There are over 10,000 references to what the color-base-fixed value would be and we would like to keep this in sync with the design system. https://global-search.toolforge.org/?q=%5C%23202122&namespaces=&title=
The `background-color-disabled` token similarly needs a `background-color-disabled-fixed` equivalent - In T370074 we needed to use this for the background of images.
== User story
As a template editor/mediawiki developer please give me fixed design tokens so that I can keep in sync with Codex.
== Acceptance criteria
- [ ] Introduce a `color-base-fixed` token that preserves the "light-mode" value for `color-base` (`#202122`) regardless of color scheme
- [ ] Introduce a `background-color-disabled-fixed` token that preserves the "light-mode" value for `background-color-disabled` (`#c8ccd1`) regardless of color scheme
