/* Mobile: Haupt-Tile groß, nächstes Tile peekt am rechten Rand (Swipe-Hint).
   Navigation erfolgt durch Swipe + Dot-Taps — die Pfeile sind hier ausgeblendet.

   Wichtig fuers smoothe Scrollen (Projekte-Track fuehlt sich besser an, weil
   beides dort NICHT passiert):
   1) Kein scroll-snap auf Mobile — jedes Einrasten unterbricht das Touch-
      Momentum. Dots + der JS-scrollTo beim Pfeil-Klick reichen als Anker.
   2) Kein scroll-behavior:smooth — stoert nativen Touch-Flow auf iOS/Safari.
   3) Keine transform/scale-Transition auf .tile.is-active — diese laeuft
      sonst bei jedem Scroll-Tick auf fast viewport-grossen Kacheln und
      ruckelt ueber die GPU. Aktive Markierung wird nur ueber Opacity geloest. */
