/*
VOICE: amable, claro y profesional; un producto para docentes ocupados, no una plantilla escolar.

PICTURE: fichas generadas (sopa de letras, flashcard, crucigrama) inclinadas como sobre una mesa.
COLOUR and TYPE: azul cobalto (tinta) dominante, coral y amarillo girasol de acento; tipografía redondeada del sistema.
LAYOUT: barra superior fija, bandas a todo el ancho, herramientas con panel de ajustes + vista previa en papel.
