/* ============================================================
   Master Tint Naranjito — hoja de estilos única para este sitio.

   Dirección de diseño: "taller de tinte / motorsport". El logo es un óvalo
   rojo/plata/negro con efecto de velocidad sobre negro, así que el sitio es
   negro racing con rojo de impacto y plata para el detalle. Tipografía
   condensada en mayúsculas (Oswald) para el aire automotriz del póster, con
   Inter para el cuerpo. Motivos sacados de su propia marca: el barrido rojo
   inclinado (el swoosh del óvalo y los realces del póster) y la cinta/marquee.
   Paleta extraída por código (colorthief) del logo y el póster:
     negro #0c0c0c/#110f0e · rojo #b31d28/#af281f · plata #bbb8ba/#c6bfbd ·
     gris neutro #5b5556.
