   Anthemon Fellowship — BASE — token, reset, utility
   ---------------------------------------------------------------------
   Mobile-first: le regole base valgono per gli schermi piccoli, i blocchi
   @media (min-width: …) aggiungono quelle per i grandi.

   Contenuto:
     1. Design token (palette, font, raggi)
     2. Reset e base
     3. Utility condivise: .container, .eyebrow, .section-title, i bottoni,
        .arrow-link

   L'ORDINE DEI FILE CONTA. Questo foglio era uno solo e la cascata ne
   dipende: piu' di una regola vince per posizione, non per specificita'.
   I file vanno caricati nell'ordine del numero in testa al nome, ed e'
   quello che fa includes/header.php. Vedi css/README.md prima di
   aggiungerne, rinominarne o riordinarne uno.

     (hue 175, sat 17%) con le ombre verdi scure, e nel quadro del pannello
     le ombre sono addirittura blu (hue 203-210). Questo e' tarato sui medi
     del quadro: piu' freddo e piu' profondo.
     Perche' non ancora piu' desaturato, che sarebbe piu' fedele: il fondo
     di Aetheria e' hue 194 sat 43%, e portando Dasos in basso i due blocchi

     il contrasto su fondo scuro, e #4D8098 su quel fondo si ferma a 3,4:1.
     La saturazione e' salita di dodici punti dopo averlo guardato a schermo:
     alla luminosita' che serve al contrasto, e a corpo piccolo spaziato,
     il teal puro (#8BB3C6) leggeva grigio sul verde invece che azzurro.

     l'accento di un altro mondo, e per giunta con questo sono quasi
     indistinguibili a occhio (delta di hue 1, di saturazione 19 punti).
