/* ======================================================================
   LOYPIN — Front v2 (auth)
   Nueva capa visual para las pantallas de acceso/registro (cliente y
   negocio). Pensada como base del rediseño del resto del sitio público:
   look de producto SaaS grande — layout de dos paneles, tipografía con
   mucho peso, espacio en blanco generoso, sin degradados ni texturas
   "de IA". Misma tipografía del proyecto (Space Grotesk / Inter).
   Producido por Cid & Engel Studio
