/*
   Theming
   -------
   The app ships DARK first. :root holds dark values; a small
   [data-theme="light"] block redefines the palette for light mode.
   The current theme is chosen in App.razor by an inline bootstrap
   script (runs before any CSS paints) that reads `iqs.theme` from
   localStorage and writes `document.documentElement.dataset.theme`.
   Default is "dark" when nothing is stored.

   New variables (--btn-bg, --input-bg, etc.) were added so that places
   where we used to hardcode #fff / #f9fafb / etc. can track the theme
   without per-selector overrides.
