   26. COMPATIBILIDAD DE PARTIALS  (añadido en T13, talaso-designer)
   -------------------------------------------------------------------------
   Los partials nav.html (T06), footer.html (T07), form.html (T08) y
   calculadora.html (T09) usan una convención de clases propia
   (.nav__*, .footer__*, .form__*, .calculadora__*) que NO coincide con la
   nomenclatura de este sistema de tokens (.site-nav, .site-footer__*, .form/
   .field, .calc). Este bloque los mapea sobre el MISMO sistema visual
   (mismos tokens, misma paleta, mismas fuentes) para que rendericen
   coherentes en estilo 14. Es ADITIVO y reversible: si algún día se
   refactorizan esos 4 partials a la nomenclatura de las secciones 13/14/18/19,
   este bloque puede borrarse sin tocar nada más.
