/* ============================================================
   Nailsmart — educativo.css
   Sistema visual de la sección educativa ("formación evaluada":
   Ciencia de la Uña en línea, la guía de verificación y las
   futuras páginas de formación).

   Identidad propia, deliberadamente distinta del sitio comercial:
   Cormorant Garamond + Source Sans 3, paleta cálida propia.

   Se carga junto a base.css. Todo vive bajo el selector .edu-theme
   para no filtrarse al resto del sitio ni colisionar con sus clases
   (.niveles, .incluye, .nota, etc. ya existen en base.css con otro
   diseño). Se aplica como clase en <body> (páginas independientes,
   p. ej. la guía) o en un <div> que envuelve el contenido dentro de
   una página que conserva el header/footer del sitio (p. ej. el
   curso).

   Requiere, en el <head>:
   <link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Cormorant+Garamond:ital,wght@0,500;0,600;1,500&family=Source+Sans+3:ital,wght@0,400;0,600;0,700;1,400&display=swap">
