Subject: css: Use CSS custom properties instead of Sass variables

In preparation for the support of prefers-color-scheme, convert all
presently used Sass variables to CSS custom properties. This will enable
us in an upcoming commit to define different values per media query.

While at it, use a better name for variables holding colours.
