/* ==========================================================================
   OBSERVADOR ARGENTINO — sistema visual
   --------------------------------------------------------------------------
   Tres decisiones gobiernan todo el archivo:

   1. TRES NIVELES DE LECTURA, exagerados. El titular pesa ~6 veces más que
      el metadato. Entre medio, la bajada. No hay cuartos niveles compitiendo.

   2. AIRE. Márgenes amplios, separación grande entre secciones, y nunca
      texto contra el borde. Entra menos contenido, a propósito.

   3. NADA DE TARJETAS. Ninguna nota vive dentro de una caja con borde,
      sombra o esquina redondeada. La jerarquía la hace la tipografía y el
      espacio; las líneas finas solo aparecen donde separan de verdad.

   El elemento distintivo es la MARGINALIA: en escritorio, las secciones y
   las horas cuelgan hacia el margen izquierdo desde una línea fina vertical,
   como las notas al margen de una publicación académica. Usa el aire en vez
   de rellenarlo, y separa el dato editorial del texto sin encajonarlo.
