/* =========================================================
   landing-quiz-ia — quiz «IA en Recursos Humanos», adaptado al sistema de diseño del sitio.

   Igual que el resto de landings de calculadora: todo va prefijado con .landing (clase del
   <body>) para ganar a styles.css sin depender del orden de carga, y las piezas del quiz
   cuelgan además de .quiz para que nombres genéricos (.panel, .op, .banda…) no se escapen.
   El JS (landing-quiz-ia.js) consulta estas clases: no renombrar sin tocarlo.

   Botones: se reutilizan .btn / .btn-primary / .btn-ghost de styles.css. Solo el botón de
   empezar tiene estilo propio, porque lleva animación.
