   SISTEMA DE DISEÑO — Thiago Rios
   Un solo archivo para todo el sitio (home, /trabajo, /blog y
   sus plantillas). Se carga desde index.html, trabajo/index.html,
   blog/index.html, trabajo/caso.html y blog/nota.html.
   Principio rector: aire, ritmo uniforme y contención (poca
   saturación). Cada sección respira con el mismo compás vertical.
