/*
 * Nenomed UI Kit — componentes visuales reutilizables de uso deliberado (prefijo nui-).
 * Nacido del rediseño del widget de Notas del dashboard; pensado para que cualquier otro
 * widget pueda adoptar el mismo lenguaje visual (icono circular con degradado, pills de
 * color, cards con sombra real, botones primario/ghost, cabecera/pie de modal) sin
 * duplicar CSS ni heredar nada por accidente -- solo se aplica donde se use la clase.
 *
 * Los colores de acento son genéricos (slate/blue/green/amber/red), no atados al
 * significado de negocio de ningún widget concreto (cada widget decide qué acento usa
 * para qué estado/categoría suya).
 *
 * INDICE
 * - Icono circular (nui-icon-circle + nui-accent-*)
 * - Card (nui-card + nui-top-*)
 * - Pill estática / badge (nui-pill + nui-pill-*)
 * - Pill seleccionable (nui-pill-select + nui-accent-border-*)
 * - Botones (nui-btn-icon, nui-btn-primary, nui-btn-pill-*)
 * - Inputs (nui-input, nui-textarea, nui-label)
 * - Chrome de modal (nui-modal-*)
 * - Fila de toggle (nui-toggle-row)
 * - Estado vacío (nui-empty-state + nui-empty-icon-*)
 * - Tabla (nui-table)
