/*
 * Smart-search widget, styled for just-the-docs v0.10.x (light scheme).
 *
 * Self-contained: the theme's own search is disabled (search_enabled: false),
 * so this file carries ALL styles for the widget — bar, dropdown panel, AI
 * answer markdown, citation cards, popular chips, feedback row.
 *
 * Palette mapped to the theme:
 *   borders   #eeebee     text      #5c5962 / #44434d / #27262b
 *   muted     #959396     washes    #f5f6fa / #ebedf5 / #ecebed
 *   accent    #7253ed (theme link purple)
 * Breakpoint: 50rem (theme "md", where .main-header becomes flex).
