/* ==========================================================================
   COMPONENTES: BUTTONS — Fase 1
   --------------------------------------------------------------------------
   Capa inicial de botones reutilizables.

   Objetivo de esta primera extracción:
   - Crear un componente real sin cambiar la apariencia vigente.
   - Mantener compatibilidad con clases legacy ya presentes en el HTML.
   - NO borrar todavía las reglas equivalentes de styles.css.

   Este archivo se carga antes de styles.css, pages/*.css, header-footer.css y
   palette-editorial.css. Por eso los estilos legacy siguen teniendo prioridad
   mientras se valida la migración.

   Compatibilidad visual Grupo 1A — botones legacy principales

   Fuente de verdad: bloque legacy efectivo de styles.css (zona ~11558).
   Objetivo: preparar la futura limpieza de reglas base en styles.css sin
   modificar la apariencia vigente.

   Importante: en esta etapa NO se eliminan reglas de styles.css. Los estados
   :hover y :disabled siguen viviendo en legacy hasta la siguiente validación.
