/* Notenzimmer — Funktionen-Hub Styles
   Phase 14: aus der Long-Form-/funktionen-Seite zur Hub-Seite umgebaut.
   7 Karten in einem Auto-Fit-Grid, jede verlinkt auf eine Detail-Seite.
   Wird auch von den Detail-Seiten (A6/A7/A8) im "Verwandte Funktionen"-
   Block genutzt — daher generische .hub-card-Klasse. */
