/* =========================================================
   Plantilla Effects — ported from Plantilla/css/style.css
   (WOW reveal, theme-title accent, case-block hover, scroll-top,
   preloader) adapted to the site's own brand blue (#0070cd) and
   typography (Poppins). Loaded on index.html, gonartrosis.html
   and protesis-de-rodilla.html for a congruent effect layer.
