// The floating search pill in the top header. One component for every module that searches
// (feed, Plex, channels, playlists): a glass rounded box with a search icon, the input, a
// clear button, and a "Go" trigger (Enter also fires it). The feed passes its live-YouTube
// escalation as the Go action; the other modules filter as you type and Go just commits/blurs.
//
// Optional slots keep the box reusable while letting one module enrich it: `leading` replaces the
// search icon with a control (Plex's search scope-pill), and `below` renders an absolutely
// positioned panel attached under the box (Plex's instant typeahead results). `onFocus`/`onBlur`/
// `onKeyDown` pass through to the input so a caller can drive that panel (open on focus, arrow-key
// navigation); the built-in Enter→Go fires only if the caller didn't `preventDefault()` first.

  // Responsive rules on the SHARED search box (every module's header, not just Plex), keyed on the
  // content column's width via `@container/appmain` (E5 S7): `min-w-0` by default so it never forces
  // overflow on a truly tiny column; once the column has room (≥420px) a `min-w-[15rem]` floor makes
  // the box WRAP to its own line via the header's flex-wrap instead of shrinking the input to ~0; on
  // a narrow column (≤640px) it also takes a full line of its own (basis-full) and sorts LAST, so the
  // small pills (module name + Plex scope toggle / feed sync chip) share the line above it.
