   Mauricio Carballo — Coaching de tenis + asesoría en inversiones
   CSS fluido: Grid + Flexbox sobre tags semánticos, custom properties,
   clamp() para tipografía fluida, variables de modo oscuro. Sin frameworks,
   sin reset pesado. Arquitectura reusada del framework de Local Webs
   (probado en templo-cafe): reveal on scroll con stagger, CTA con shine,
   nav con glass al scrollear — sin scroll-snap (se probó ahí y se sacó
   porque se sentía como un salto brusco; no se repite acá).
