   Jellyfin Music Ingestion — design tokens
   Palette: quasi-nero caldo (non il solito nero+verde acido) con un
   accento oro/vinile, per richiamare l'attrezzatura audio analogica
   senza scadere nei default "AI generated" (crema+terracotta o
   nero+verde acido). L'elemento firma sono le barre stile VU-meter
   usate per il progresso dei download.
