Portrait de couple en plein jour converti à l'heure bleue

Transform the uploaded daytime lakeside couple portrait into a realistic blue-hour evening scene. Preserve both people’s exact identities, ages, expressions, embrace, body poses, navy-and-cream knitwear, pier, lake, hills, camera angle, framing and crop. Change only the time of day and lighting: deepen the sky to cobalt blue, darken the wooded hills naturally, add subtle warm lights along the distant shore and their reflections, introduce cool ambient light with a gentle realistic rim light on hair and shoulders, and update every shadow and reflection consistently. Do not alter faces, clothing, anatomy, background geometry or add new foreground objects.
