/* Vlad Zaha: profil personal.
   Runda 2: mai uman și mai cald. Fundal luminos cald (nu alb pur), accentul e verdele-salvie
   din cămașa din portret. Literata pentru titluri (o literă de carte, caldă), Figtree pentru text.
   Runda 3: hero-ul și contactul sunt întunecate, într-un verde-negru cald (--dark); conținutul dintre ele rămâne luminos.
   Fără italic, fără text peste poze.
   Colțuri: butoanele sunt pastilă, pozele și cardurile au 14px. */
