SnapOtterandGitHub 00b651c9f8 feat(i18n): 21-language pipeline, landing/docs/API wiring, landing+API translations

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.

Add solid-color bars to fit a target aspect ratio.

Aspect Pad

Add solid-color letterbox or pillarbox bars to fit a video into a target aspect ratio without cropping.

API Endpoint

POST /api/v1/tools/video/aspect-pad

Accepts multipart form data with a video file and a JSON settings field.

Parameters

Parameter	Type	Required	Default	Description
target	string	No	`"9:16"`	Target aspect ratio: `16:9`, `9:16`, `1:1`, `4:3`, `3:4`
color	string	No	`"#000000"`	Hex color for the padding bars (e.g. `"#000000"` for black)

Example Request

curl -X POST http://localhost:1349/api/v1/tools/video/aspect-pad \
  -H "Authorization: Bearer si_your-api-key" \
  -F "file=@clip.mp4" \
  -F 'settings={"target": "1:1", "color": "#ffffff"}'

Example Response

{
  "jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/clip.mp4",
  "originalSize": 12500000,
  "processedSize": 13200000
}

Notes

If the video already matches the target aspect ratio, the file is returned unchanged.
Use 9:16 for vertical/portrait social media formats (TikTok, Reels, Shorts).
For blurred padding instead of solid color, use the Blur Pad tool.
