/* ==========================================================================
   AXR-Systems — Einsparungs- und ROI-Rechner.

   Nutzt dieselben Bausteine wie Sichtbarkeits- und KI-Check (.ax-sc-*,
   .ax-grades, .faq-item), damit die drei Werkzeuge als ein System gelesen
   werden. Eigene Datei, weil sie nur auf der Rechnerseite geladen wird.

   Aufbau: links Eingaben, rechts eine mitlaufende Ergebnistafel. Die Tafel
   klebt am oberen Rand, damit die Zahl beim Schieben der Regler immer im
   Blick bleibt — das ist der eigentliche Grund, warum jemand hier ist.
