/**
 * ============================================================
 *  Latido Familiar - style.css (DOCUMENTADO)
 * ------------------------------------------------------------
 *  Este archivo define TODO el estilo visual de la webapp:
 *  - Paleta de colores (variables CSS en :root)
 *  - Tipografías y jerarquías (títulos, subtítulos, textos)
 *  - Layout (contenedor principal, grids responsivos)
 *  - Componentes (cards, botones, avatares, mensajes)
 *  - Interacciones y animaciones (hover, fade, slide, pop, bounce)
 *  - Elementos especiales:
 *      • Composer flotante (barra fija inferior)
 *      • Acordeones (historial)
 *      • Modales (ver mensaje y responder)
 *      • “Sobre sorpresa” para mensajes no leídos
 *      • Badges de notificación
 *      • Toast flotante (mensaje de éxito)
 *
 *  Nota importante (posible bug):
 *  - En `.msg-card.compact` usas `border-left: 4px solid var(--muted);`
 *    pero `--muted` NO existe en :root.
 *    → Lo correcto sería usar `var(--text-muted)` o crear `--muted`.
