Shared Claude Code translation pipeline (scripts/i18n, no API key) plus Astro/VitePress/Scalar i18n wiring. Landing and API reference translated into all 20 languages; docs i18n wiring + English source anchors. The translated docs markdown (apps/docs/<locale>/**, 3,620 files) follows in a companion PR because it exceeds GitHub's per-PR CI file limit.

## Notes {#notes}
|
|
|
|
- If the video has no audio track, the request returns a 400 error.
|
|
- MP3 is lossy but widely compatible. WAV is lossless but large. M4A (AAC) offers a good balance of quality and size. OGG is available for open codec workflows.
|
|
- When the source audio is already AAC and the output format is M4A, the audio stream is copied without re-encoding.
