All 181 docs markdown files translated into 20 languages (apps/docs/<locale>/**). Companion to the i18n code PR; admin-merged because the file count exceeds GitHub's per-PR CI trigger limit. Validated by pnpm i18n:check (all surfaces, 0 stale/missing) and a clean all-locale docs build.

## Notes {#notes}
|
||
|
||
- 上传两个文件：第一个必须是视频，第二个必须是字幕文件（.srt、.vtt 或 .ass）。
|
||
- 内嵌的（软）字幕可由观看者在其媒体播放器中切换。若需要永久可见的字幕，请改用 Burn Subtitles 工具。
|
||
- 语言代码以元数据形式存储在容器中，有助于媒体播放器为字幕轨道标注标签。
