/* ==========================================================================
   Notte, una sola sorgente di luce, una serif.

   Regole, e tutto il resto scende da queste:
   1. Il fondo è quasi nero e la luce arriva da un punto solo, il pettine
      dell'hero. Il resto della pagina ne riprende solo il segno: la riga
      sotto la barra e i righelli fra le sezioni.
   2. I titoli sono in Instrument Serif. Il corsivo è un accento, uno solo.
   3. Il monospace serve solo a ciò che si conta: date, misure, unità, nomi
      di repository. Sempre in minuscolo normale, mai spaziato.
   4. Niente schede, pillole, vetro, frecce, stelle, ombre colorate.
      Le cose si separano con una riga da 1 px e con lo spazio.
   Una pagina sola, nessun framework, nessun build step.
