Begin on the frame described. Camera locked off, no movement. First two seconds: complete stillness, eyes fixed off-camera-left, no blink at all. Seconds two to four: a single slow blink, and on the reopen her eyes have not moved — they return to exactly the same point. Seconds four to five: the smallest possible tightening at the outer corners of the eyes, no more than a millimetre, with nothing else in the face changing at all. Final second: stillness returns fully. Two blinks total, the second one late and slower than the first. Breathing shallow and high in the chest, barely visible at the shoulder line, one held inhale across the middle of the shot that is not released. Focus holds on her near eye throughout, no rack. Overhead light constant, the shadow in the eye sockets unchanged. Faint haze drifts through the ring beams in the upper frame; a single curl at her temple settles a few millimetres and stops. Ends on her face exactly as it began, eyes fixed off-camera-left, mouth closed, expression unreadable. Motion add: smiling, eyebrow raise, head turning, nodding, mouth opening, emotional performance
