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.

# Blur Pad {#blur-pad}
Fit a video into a target aspect ratio by filling the padding area with a blurred, scaled copy of the video instead of solid-color bars.
## API Endpoint {#api-endpoint}
`POST /api/v1/tools/video/blur-pad`
Accepts multipart form data with a video file and a JSON `settings` field.
## Parameters {#parameters}
| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| target | string | No | `"16:9"` | Target aspect ratio: `16:9`, `9:16`, `1:1`, `4:3`, `3:4` |
| blur | number | No | `20` | Gaussian blur sigma for the background (2-50) |
## Example Request {#example-request}
```bash
curl -X POST http://localhost:1349/api/v1/tools/video/blur-pad \
-H "Authorization: Bearer si_your-api-key" \
-F "file=@clip.mp4" \
-F 'settings={"target": "16:9", "blur": 30}'
```
## Example Response {#example-response}
```json
{
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/clip.mp4",
"originalSize": 12500000,
"processedSize": 14100000
}
```
## Notes {#notes}
- Higher blur values produce a softer, more abstract background. Lower values keep more detail visible.
- If the video already matches the target aspect ratio, the file is returned unchanged.
- For solid-color padding, use the Aspect Pad tool instead.
