/*
  Kinderspiele App-Basis
  ======================

  Diese Datei ist die zentrale Stelle für alle gemeinsamen Maße, Farben,
  Buttons, Karten, HUD-Leisten, Topbar und Spielfeld-Rahmen.

  Für neue Spiele gilt:
  - Rahmen, Topbar, HUD, Buttons und Spielfeldgröße bleiben hier zentral.
  - Das jeweilige Spiel-CSS enthält nur noch spielbezogene Elemente.
