   REDISEÑO 2026-08 — azul de marca al mando, verde para la acción
   ------------------------------------------------------------------
   Reparto aproximado 70/30: el azul ordena (cabecera, panel de entrada,
   títulos) y el verde marca lo accionable (botones, foco, burbuja del
   visitante, filete del asistente). Antes el verde competía con el azul
   en superficie y el conjunto se veía disparejo.
   La ventana crece a 920px porque las respuestas del asistente son
   largas, y la pantalla de entrada pasa a dos paneles: en una ventana
   ancha, un formulario de dos campos centrado dejaba medio widget vacío.
   Este bloque va al final a propósito: sobrescribe lo anterior sin
   tocarlo, así el diseño previo queda de referencia en el archivo.
