/* ===========================================================================
   Gato Curioso — folha de estilo unica.

   Direcao: o conteudo e rigoroso (estudo, ano, universidade) e a marca e
   brincalhona (gato laranja de lupa). O site resolve isso como uma revista de
   curiosidade: tipografia editorial, papel quente, muito respiro — e o laranja
   entrando so como acento, nunca como cenario.
