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.

## API Endpoint {#api-endpoint}
`POST /api/v1/tools/pdf/nup-pdf`
Accepts multipart form data with a PDF file and a JSON `settings` field.
## Parameters {#parameters}
| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| perSheet | integer | No | `2` | Pages per sheet: `2`, `3`, `4`, `8`, `9`, `12`, or `16` |
## Example Request {#example-request}
```bash
curl -X POST http://localhost:1349/api/v1/tools/pdf/nup-pdf \
-H "Authorization: Bearer si_your-api-key" \
-F "file=@document.pdf" \
-F 'settings={"perSheet": 4}'
```
## Example Response {#example-response}
```json
{
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/document.pdf",
"originalSize": 2450000,
"processedSize": 2300000
}
```
## Notes {#notes}
- Pages are arranged in reading order (left to right, top to bottom).
- The output page size matches the original; individual pages are scaled down to fit the grid.
- A 20-page document with `perSheet: 4` produces a 5-page output.
