/*
 * Header search: a command-palette-style overlay.
 *
 * Its own sheet, same reasoning as newsletter.css and article.css: a
 * component with a dialog, an animated backdrop, a live-typeahead list and
 * four states (idle / loading / results / empty) is easier to reason about
 * whole than folded into brand.css.
 *
 * Native <dialog> in the top layer, so nothing here fights the sticky
 * header or the cookie banner for z-index and none is set (same trick as
 * .c-nl in newsletter.css).
 *
 * COLOUR NOTES, same measured palette as the newsletter modal:
 *   #FFFFFF on #7C5CFC   4.38:1   the active result row, the "view all" pill
 *   #FFFFFF on #0D0D0F  19.5:1    the search bar
 *   #B3B3B3 on #141416   9.1:1    meta text (category / date)
 *   #9478FD on #141416   5.4:1    accent used as small text
