/* ===== Search Dialog =====
   Styled after Algolia DocSearch v5's visual language - the dimmed scrim,
   the recessed modal, card-like hit rows with a soft drop shadow, the
   keyboard-hint footer - so the dialog reads the way a doc site does.

   Deliberately not @docsearch/css: that package is only licensed for
   eligible documentation sites and would add a bundled dependency to a
   project that ships zero of them. Colours come from the --in-* tokens
   rather than DocSearch's own --docsearch-* set, which keeps dark mode
   automatic and stays inside the project palette.

   Mapping: --docsearch-primary-color -> --in-color-accent,
   --docsearch-muted-color -> --in-color-muted,
   --docsearch-modal-background -> --in-color-subtle,
   --docsearch-hit-background -> --in-color-bg.
   Skipped: the breadcrumb. DocSearch assumes a lvl0..lvl6 heading tree;
   records here are one per post with no hierarchy to show.
