Vercel Deployment: Stale URL Resolves to 404 Error

Bug Description
Ese mensaje significa que la URL apunta a un deployment que ya no existe (o nunca existió) dentro de tu proyecto de Vercel.
En Vercel cada build genera un subdominio único (por ejemplo portfolio-ux-git-main-…vercel.app). Cuando subes uno nuevo, los deployments viejos se pueden borrar automáticamente (garbage-collection) o pasar a estado archived. Si alguien intenta abrir la dirección antigua, Vercel ya no la encuentra y devuelve ese 404 especial.
