/* ==========================================================================
   AUREON HELIX — indexV2.css
   Hoja única para indexV2.html. Orden de cascada:
     1) hero.css          — Hero, sin cambios
     2) site.css          — sitio, sin cambios
     3) refinamientos     — acabado (grano, luz, filos, superficies)
   El bloque de refinamientos va al final a propósito: sobrescribe por
   cascada, no por !important, así que puede quitarse borrando ese tramo.
