# Sistema de Botones Consistentes - iqEngi

Este skill define los estilos de botones estándar para mantener consistencia visual en todo el proyecto.

## Filosofía de Diseño

- **Jerarquía Visual**: Primary para acciones principales, Outline para secundarias
- **Consistencia**: Mismo hover, transiciones y tamaños base
- **Accesibilidad**: Contraste AA garantizado con `text-white` sobre primary
