/* ERP EMTEL v3.38 — estándar transversal de movimiento fluido.
   Reglas obligatorias:
   1) toda transition vive en el estado base;
   2) las apariciones usan opacity + transform + pointer-events;
   3) el movimiento usa la curva orgánica EMTEL;
   4) el borde luminoso usa padre/::before/hijo, nunca border-color animado. */
