Animate only the surrounding friends. They casually talk to each other, exchange small gestures and occasionally laugh with natural restrained movements. The woman in the white sweater in the center must remain almost completely still, like a stable photographic anchor of the shot. Preserve her exactly from the source image frame by frame. Do not animate her face. Keep her exact original facial expression, closed-mouth subtle smile, exact mouth shape, lips fully closed, exact eyes, nose, jawline, cheeks, skin texture, facial proportions, hairline, hairstyle, hair length, hair volume, and every strand silhouette unchanged. She does not speak, does not laugh, does not open her mouth, does not show teeth, does not move her lips, does not change expression, does not turn or tilt her head. Do not generate additional hair, change the hairstyle, increase hair volume, move the hair, or alter the silhouette around her head. No facial morphing, identity drift, expression change, teeth generation, beauty enhancement, face reconstruction, or hairstyle reconstruction. Her body also remains nearly still in the original pose, with only imperceptible natural breathing if necessary. All visible motion comes primarily from the other people around her. Preserve the exact original composition, identities, clothing, positions, room, furniture, objects, lighting, colors, shadows, and warm party atmosphere. Static locked-off camera. No camera movement, no zoom, no pan, no tilt, no reframing, no shake.
