/* ==========================================================
   C&L Energia Solar — estilos
   Leitura em coluna única, como uma conversa: medida de 62 caracteres,
   faixas de gravura (xilogravura de cordel) rompendo a largura total.
   Papel quente, tinta de tipografia, acento azul-anil; carmim só dentro
   das gravuras e em marcadores pequenos. Sem card, sem grid, sem sombra.
   A textura de papel entra só nas faixas de gravura, nunca atrás de parágrafo.
