/* ====================================================================
   Lector interactivo — componente compartido
   ====================================================================
   Texto con palabras que se tocan para ver traducción + nivel CEFR,
   preguntas A/B/C y caja de resultado. Lo usan:
     - template-parts/daily-story-modal.php  (Historia del Día, home)
     - reading-activity.php                  (actividades de tipo lectura)
   El JS está en assets/js/hsc-reader.js. Usa los tokens "dh" de tokens.css.

   Los selectores van precedidos de .hsr-scope donde hace falta ganar a las
   reglas globales por etiqueta de luz-saber.css (span, label, p…).
