/* ---- Native bridge transport gating -------------------------------------
   Which print transport is available can only be decided client-side: the
   Hotwire Native Android WebView sends a plain user agent on its HTTP
   requests, so the server cannot detect the app. The bridge JS stamps
   data-bridge-components onto <html> when the native adapter attaches, which
   is the reliable signal — and it is version-aware, so an old APK without the
   thermal-print component correctly keeps the web variant.

   Default (no native bridge): show the Web Bluetooth row, hide the native one.
