In dark mode, the text on alerts does not have enough contrast. Error alerts are dark red on medium red, warnings similarly poor for the same reasons.

Warning banner content color is not obvious. See in rancher/dashboard#15665

On the Longhorn overview page, the description text has the same color as --body-bg, making it invisible in both light and dark themes. See rancher/dashboard#15690.
