/* Olomni · Olo Studio — sistema visual del sitio (portada, novedades, guías y documentos).

   DIRECCIÓN: «keynote con cara». Capítulos que alternan blanco y negro, como una página de producto de Apple: el cambio
   de fondo marca el cambio de idea. Titulares Geist muy grandes con tracking negativo y un único acento ultramar.

   LO QUE LO HACE DE OLOMNI (no de Apple): la identidad sale de la cara de Olo.
     · Los ojos: la marca y un pequeño compañero (solo con ratón) miran hacia tu cursor.
     · La sonrisa: la palabra clave de cada titular se subraya con la sonrisa de Olo, trazada al aparecer.
     · El marco 9:16: las esquinas de visor que rodean todo lo que Studio produce.
     · La perla: el cuerpo de Olo (#ece7dc) es el único color cálido en un mundo negro y azul.

   Movimiento, un solo lenguaje: sube 28 px + opacidad, 0.9 s, cubic-bezier(.16,1,.3,1). Solo transform y opacity. */
