/* ==========================================================================
   CALVIRA — dirección de arte editorial
   Redesign overhaul. La estructura y los textos se conservan; el lenguaje
   visual se reemplaza: menos cajas, menos filetes, más aire, más tipografía.

   REGLA DE COLOR (no la rompas al editar):
   el rojo señal marca la LECTURA, el DEFECTO o la ACCIÓN.
   Lo que ya está dentro de especificación se imprime en grafito, nunca en
   verde y nunca en rojo. Por eso el "antes" va en rojo y el "después" en
   grafito, y por eso el 0 de cuentas comprometidas va en grafito.

   MODO: la página está comprometida con el papel claro. El fondo tinta es un
   recurso de composición (dos secciones), no un tema alternativo. Invertir la
   página entera destruiría ese recurso, así que no hay dark mode y es una
   decisión declarada, no un olvido.
   ========================================================================== */
