四步到窗前拉开窗帘（精确动作分解）

Style: Quiet drama, naturalistic, soft window-light cinematography, muted earth-tone palette of amber, cream, walnut brown. A narrow apartment bedroom at late morning. A wooden floor, an unmade bed in soft shadow, sheer curtains drawn shut over a tall window. Pale light bleeds through the fabric. An actor in a simple linen shirt stands a few paces from the window, hesitating. Cinematography: - Camera: medium-wide, locked off at eye level; one slow micro-push toward the window - Lens: 50mm; shallow DOF, sharp on the actor - Lighting: soft window light as key; warm lamp fill on the bed; cool rim from hallway - Mood: contemplative, tender, quietly hopeful Actions: - Actor takes four steps to the window - Pauses, hand hovering near the curtain - Inhales once - Pulls the curtain open in the final second; daylight floods the room Background Sound: Floorboard creak under each step; fabric slide of the curtain; distant city hum beyond the glass. No music.
