/* =====================================================================
   Línea de tiempo del cronograma (preuniversitariotesla.cl/cronograma/),
   oct-2026. Lenguaje Scrolltide: portada nocturna con aurora, cifras que
   cuentan (Lime Metrics), riel de meses que se llena al bajar (el scrub de
   Katana) y una línea dorada que se enciende con el scroll. Todo con CSS y
   un JS chico: nada de WebGL, que en celulares sin GPU hundía PageSpeed.
   Los datos salen en vivo de /api/cronograma-publico (módulo Cronogramas).
