/* Chart Maker — landing
   La identidad viene de la app de Mac: negro casi puro, el verde de las barras
   y una condensada para los titulares. Las clases son las mismas que
   /charlatan/ y /guardianreader/ para que los tres sitios se sientan uno; lo
   que cambia acá es la paleta y que las capturas son de escritorio, no de
   teléfono — de ahí .mac en vez de .phone. */
