/* ============================================================
   Seurch plan & checkout pages (private build).

   Styled with the open core's design tokens, exposed as CSS variables by the
   committed search/tailwind.css and re-pointed under `.dark` and
   `.theme-system` (dark scheme), so every colour here flips automatically in
   dark mode. Like landing.css, tokens are read with light-mode fallbacks.

   This is a standalone stylesheet because the private build intentionally
   does not run the open core's Tailwind CLI pipeline: a utility class the
   core's own templates don't use is tree-shaken out of the committed build,
   so overlay pages cannot rely on arbitrary utilities being present.
