At medium and high contrast, secondary-container turns dark. The empty
part of progress bars, highlighted code lines and a targeted roadmap
header now use surface-container-highest, so the fill and the text stay
readable. The selected project in the project jump is light at these
levels too; its check mark marks it.
The selected sidebar query gets the pill style even with its "clear"
icon next to it. The icon sits inside the pill and takes the pill's
text color.
