/* ============================================================
   "Open in your browser" nudge for LINE / Facebook / Instagram's
   in-app WebView.

   Those apps run an isolated cookie jar/storage from Safari or
   Chrome, so score.sportz.jp login state doesn't carry over when
   a link is opened inside one of them. Docked at the TOP (not the
   bottom, where pwa-install.css's card lives) so the two never
   overlap.

   Injected + controlled by in-app-browser.js.
