/* v833: body scroll-lock REMOVED.
   In iOS WKWebView installed PWA standalone mode, setting
   `overflow: hidden` on <body> while a fixed-position panel is on top
   silently suppresses the soft keyboard when an <input> inside the
   panel is tapped. Focus lands on the input but iOS never raises the
   keyboard. The panel itself is `position: fixed; inset: 0;` so the
   landing screen behind it can't scroll-leak anyway — the body lock
   was redundant AND actively harmful. Class name kept so any future
   per-panel rules can still hook off body.shelfd-auth-page-open. */
