/**
 * main.css — Estilos críticos y globales MPYP-Pro
 * Version: 2.1.0
 *
 * DECISIONES TÉCNICAS:
 * - CSS custom properties (variables): design tokens centralizados.
 * - Mobile-first: min-width media queries.
 * - :focus-visible (no :focus): outline solo en navegación por teclado.
 * - prefers-reduced-motion: respetamos configuración del usuario.
 * - scroll-padding-top: WCAG 2.2 Focus Not Obscured (no dejamos focus detrás del header).
 * - :target offset: anclas no quedan bajo sticky header.
 * - Target Size mínimo 44×44 para elementos interactivos (WCAG 2.2 ≥ 24×24, optamos por 44).
 * - Container queries con fallback: componentes responsivos sin depender solo del viewport.
