/*
 * =============================================================================
 * COMPONENTES BASE — Sistema visual 1.0, Fase C
 * =============================================================================
 *
 * Botones, campos (normal · hover · foco · error · deshabilitado), casillas,
 * toggle segmentado, pestañas, tabla, estados editoriales y diálogo.
 * Sólo fichas de tokens.css: ningún color literal (salvo el blanco de la
 * palomita, que va sobre --accent en ambos temas).
 *
 * Movimiento: lo repetitivo (hover, marcar, seleccionar filas) sólo cambia de
 * color en --dur-instant; pestañas en --dur-fast; diálogos en
 * --dur-deliberate. Una curva (--ease) que no se pasa de 1: sin rebotes.
 * Con "reducir movimiento", base.css anula animaciones y transiciones.
 *
 * Foco: siempre visible y con --accent sólido (≥ 3:1). En los campos, además
 * del borde --accent, un anillo --accent-soft de 3 px.
 * =============================================================================
