Subtle idle animation

Subtle idle animation. The subject stays in place and breathes slowly and naturally, chest and shoulders rising and falling. A gentle, slow head and upper-body sway with a faint vertical bob. Occasional soft, natural eye blinks. Hair drifts lightly as if in a faint breeze. Static locked-off camera, no pan, no zoom, no camera shake. Minimal motion, smooth, calm, seamless looping.
