   Todo vai dentro de .tv para non tocar o tema. A tipografía hérdase do tema;
   os bordos e os fondos calcúlanse a partir da cor do texto (--tv-text).
   Para cambiar a cor principal, define --tv-accent no CSS adicional do tema:
   .tv { --tv-accent: #c0392b; }                                            */
