月明かりの部屋で揺れる銀髪

Prompt

An adult anime woman with long silver hair stands in a moonlit room, wearing a black evening dress, face identity constant. Her hair sways gently from side to side along the horizontal axis, small amplitude, slow rhythm, about once every two seconds. The hem of her dress moves in the same rhythm, half a beat after her hair. Her chest rises and falls softly with calm breathing along the vertical axis, subtle and steady. Her eyes blink slowly, gaze fixed toward the large window. Moonlight flickers faintly across the room, casting soft shadows that shift with the clouds. Soft ambient room tone and the faint rustle of fabric are heard in rhythm with her movement. Camera locked, same angle as the reference image, no zoom, no shake, real-time speed. The rhythm continues evenly to the final frame for a seamless loop.
