+
+## Notas
+
+Cada linea recibe un color de la paleta distribuido proporcionalmente: `colorIndex = (i * len(colors)) / totalLines`. Para ASCII art con pocas lineas, usar una paleta corta. Para muchas lineas, una paleta larga da transiciones mas suaves.
+
+`DefaultGradientColors` es una variable publica con 8 colores (purple->blue->cyan->red) que se puede reasignar si se desea cambiar el default global.

+
+Patron de uso: cada app TUI mantiene un directorio `static/` con archivos `.txt` de ASCII art. Al iniciar, `LoadASCIIArt` elige uno al azar y le aplica el degradado de colores. Esto da variedad visual en cada ejecucion.
+
+Fallback silencioso: si el directorio no existe, no tiene .txt, o hay error de lectura, retorna "" sin error. El caller decide si mostrar un fallback.
