/* ==========================================================================
   /industria/ · diseño E "El plano de tu operación" (rediseño de marca,
   oct-2026). Prototipo: prototypes/marca-2026-10/e/.

   La página es una lámina de dibujo: papel vegetal con cuadrícula, un marco
   con cajetín, y la operación dibujada como maqueta isométrica. El único
   color es el color del dato.

   Como en el home, aquí se redefinen los tokens de styles.css sobre
   body.ind-e: el nav, el pie y las preguntas toman la paleta y la tipografía
   del plano sin cambiar su markup.
