H3 全参考改写：让参考视频里的人说话 · 4 秒快测H3 full-reference rewrite: make the referenced subject speak · 4s quick test

以参考视频为底、参考音频为音色，让画面里的人物说出指定台词。提示词走 H3 的六段式结构，重点是 retention_analysis——逐条声明每个参考项是完全保留、部分复用还是仅作参考，说不清就会出现改了不该改的地方。【4 秒快测版】内容与原版一致，压到 4 秒用于试参数、试素材、试机器，不用于出成片。

Full-reference rewrite: keep the source video, make the person in it speak your line in a referenced voice timbre. [4s quick test] Same content as the full-length version, cut to 4 seconds for checking parameters, assets and hardware — not for final delivery.
