/* ══════════════════════════════════════════════════════════════════════════
   DARK THEME — internal Knowledge app (ENG-1354)
   ══════════════════════════════════════════════════════════════════════════
   Additive only, same invariant as the block at the end of public_kb.css: a
   `:root[data-theme="dark"]` token remap plus existing light selectors prefixed
   with `[data-theme="dark"]`. No light declaration is edited, no `!important`.

   Why the token remap wins: the vendored design-system.css declares its 133
   `--tw-color-*` tokens on an UNLAYERED `:root,:host` (0-1-0), so
   `:root[data-theme="dark"]` (0-2-0) beats it on specificity — which matters
   because design-system.css loads AFTER this file.

   The page background and body colour come from public_kb.css's `body` rule
   (that file is glob-loaded here too), so the neutral/background hexes in the
   two files are deliberately identical.

   Hex literals appear only as TOKEN VALUES — defining a theme's palette is not
   the ad-hoc colour use docs/design-system.md rule 7 prohibits, and every
   non-token rule below reads a var().
