不用重拍，直接接着往下拍：模型读最后几帧，保持同一个人物、构图和声音继续生成。5 秒的输入会变成 10 秒的输出，接缝基本看不出来。

The scene continues from the final visor close-up: same woman inside the EVA helmet—pale luminous skin, light blonde hair, striking clear blue eyes, calm wonder—same teal-and-orange helmet lighting, cyan on the upper face and visor edge, intense orange from below on lips and chin, dark charcoal bokeh, fine glowing particles. Keep everything else the same; no new characters, no cutting away to a different location.\n\n[0-1.6s] Orange console glow brightens further as a soft alert pulse; her eyes track a reflection sliding across the curved helmet glass; quiet breath inside the suit.\n[1.6-3.4s] Soft millimeter push-in on the nearest blue eye; orange caustic flickers on the lower lid; a single particle drifts past the glass.\n[3.4-5s] Slight pull-back revealing more of the visor curve; she blinks once slowly, then holds the calm upward gaze as the ethereal pad swell resolves into a slow rising chime.\n\nAudio continues: soft suit air recirculation, faint console beep, muffled distant hull creak; ethereal pads with a slow rising chime.
