/* ============================================================
   Hque design tokens
   --------------------------------------------------------------
   GitHub Primer-derived token vocabulary. Defines :root for
   light mode and [data-theme="dark"] for dark. Consumed
   directly by all *.razor.css and hque-overrides.css; mirrored
   verbatim in C# at Theme/HqueTheme.cs for MudBlazor (which
   types palette properties as MudColor and won't accept
   var(--…) strings).

   The legacy alias bridge that PRs 1–3b carried (--text,
   --surface, --accent etc.) is gone — all consumers migrated
   to these direct names by PR `theme/que-ui-sweep`.
