   caudal.puaj.club · monitor de los ríos Paraná y Uruguay
   La página adopta la estética de puaj.club: papel gris de los primeros
   navegadores (Mosaic/Netscape) en claro y modo texto de BBS/DOS con paleta CGA
   en oscuro; monoespaciada, botones entre corchetes, secciones como #canales.
   Los gráficos siguen siendo figuras de matplotlib incrustadas: panel propio,
   ejes en caja negra fina, marcas afuera, DejaVu Sans.
