   unpräfigierte Variablennamen (--fg, --line, --card, --gold, ...), die in
   diesem Projekt nie definiert wurden — hskReaderV2.v1.css kennt nur die
   v2-präfigierten Varianten. Dadurch blieben z. B. Memory-Karten-Hintergründe
   im Dunkelmodus hell fest codiert (#fff8ee-Verlauf), während die (geerbte,
   korrekt umgeschaltete) Textfarbe hell wurde — helle Schrift auf hellem
   Hintergrund, praktisch unlesbar. Aliase auf das bestehende, bereits
   Hell/Dunkel-fähige --v2-*-System beheben das für die ganze Datei auf einen
   Schlag, ohne die ~700 Regeln einzeln anzufassen.

   im Dark Mode hell -- praktisch unlesbar. Text fest dunkel; Hover bekommt
   eine deutlich sichtbare, helle Gold-Markierung statt der zu dunklen
   var(--hl2), die im Dark Mode kaum vom Panel-Hintergrund zu unterscheiden
   war ("hover nicht erkennbar"). */
