/* DespedidoPorIA — design tokens + componentes custom
 *
 * Tokens (CSS variables) reflejan el sistema de diseño aprobado.
 * Tailwind atómico cubre el grueso; este archivo agrega:
 *   1. Tokens (colores, escala, sombras, radios, transiciones).
 *   2. Componentes complejos (problema-card, timeline, testimonio-card,
 *      garantia-card, FAQ details, calculadora inputs).
 *   3. Animaciones (fade-up, bounce-subtle, pulse-glow).
