The accessibility audit made the quiet text greys dark for every theme, and
old rules never followed the dark themes: Card Settings drew white text on
light grey blocks, popup items, the sidebar's shortcuts row, quiet buttons and
sidebar labels were black on dark, and an !important list header beat each
theme's own. The quiet text is a variable with a light value on the dark
surfaces; Card Settings' sections, popup items and the other rules follow the
theme. axe-core finds no colour contrast failure in cleandark, moderndark, dark
and exodark on the board, sidebar, Card Settings, an opened card and the custom
fields popup.
Thanks to Samunosuke and xet7 !
