/* =============================================================
   ROOM VERIFY OVERLAY  (combination-lock style)
   Generische Komponente - verwendet von Roomservice + Bookings.

   Verwendung: Ein Container mit .room-verify (+ .open zum Oeffnen)
   enthaelt .room-verify-inner mit Titel, Subtitle, Error, Digits
   und Actions. Einzelne Digit-Walzen tragen .rv-digit-col, dessen
   Inhalt .rv-digit-arrow (Chevron up/down) und .rv-digit-val (Zahl)
   umschliesst.

   Der Roomservice nutzt diese Klassen auch fuer den Time-Picker
   (#rs-tpick-digits): dort wird .rv-digit-col mit data-time-col
   verwendet - Markup ist bis auf das data-Attribut identisch.
