   BlackArchive — shared stylesheet
   Dark is the default. Every colour is a token, so the light theme is a pure
   variable swap and no component rule is duplicated per theme.
   All text/background pairs are verified against WCAG AA (4.5:1) at their
   rendered size — see backend/scripts/contrast_check.py.
