   Coroto — sistema visual
   ---------------------------------------------------------------------
   Línea de diseño (ver docs/ARQUITECTURA.md §6): club de arte, no panel
   corporativo — grafiti / pintura / tatuaje / ambiente relax, con
   personalidad, sin cansar la vista en uso prolongado (turno de noche).
   Compromiso deliberado: identidad expresiva en headers/acentos, alta
   legibilidad en datos/números (esto es una caja registradora, no un
   afiche) — tipografía display solo donde no compromete lectura rápida
   de precios y cantidades.
