/* Midnight theme pack ("Тёмная тема"): the true dark scheme.
   color-scheme: dark flips native widgets/scrollbars; Bootstrap follows via
   data-bs-theme="dark" (owner: rewards.theme_service.bootstrap_theme_for_slug).

   The pack overrides system-wide semantic tokens only; domain token owners
   carry their own [data-ui-theme="midnight"] blocks next to their :root
   defaults (header/_tokens.css, cabinet/base_modules.css, cabinet/ai.css,
   css/utilities.css). ContentColor and RichContentTone stay theme-independent.

   Accent policy:
   - buttons use the wallpaper-derived aurora control ramp on 90% graphite plates;
   - action *text* (links, active tabs) moves to brand-300 which is readable
     on night surfaces;
   - feedback roles move to mid-light hues readable as text on night surfaces;
     toast solid backgrounds are pinned back to the strong primitives. */
