/* =============================================================================
   PLENAUT — Frontend Design System
   Trust & Authority + Swiss Modernism 2.0

   Palette monocromatica: un'unica tinta (verde petrolio Pantone 821C) declinata
   in una scala 50→950. Neutri desaturati sulla stessa tinta. Nessun colore
   decorativo secondario, nessun gradiente multicolore: la gerarchia si costruisce
   con valore (chiaro/scuro), peso tipografico e spazio.
   I colori di feedback (successo/attenzione/errore) sono l'unica eccezione,
   perché lo stato non può essere comunicato solo dalla tinta di brand.
