/* ============================================================================
   EcuTunerx — the public chat widget.

   Self-contained: every token it needs is declared on .ecux-w with a fallback,
   so the widget looks right on a page that has NOT loaded site.css, and adopts
   the page's own palette where it has. A support widget that only renders
   correctly on some pages is a support widget nobody trusts.

   The visual direction is the site's, not a chat vendor's: cream paper, ink
   type, thin burgundy rules, Fraunces for anything that carries weight. It
   should read as part of EcuTunerx rather than a bolted-on third-party box —
   no rounded-blue-bubble house style, no gradient launcher.
   ========================================================================= */

/* An element this widget marks hidden must actually be hidden. The UA rule
   `[hidden] { display: none }` loses to any class that sets a display value,
   and `.ecux-transfer`/`.ecux-ident` both do — so without this the transfer bar
   and the email capture rendered before there was a conversation to transfer
   or an address to attach. admin.css carries the same guard for the same
   reason; widget.css needs its own because it never loads alongside it. */
