iPad 13 screenshot preset.

Example request

{
  "canvas": { "preset": "appstore.ipad_13" },
  "slides": [
    {
      "headline": { "lines": ["Ship store assets", "from CI"] },
      "screenshot": { "url": "https://example.com/captures/home.png" }
    }
  ]
}

Reference table

Use the preset instead of raw dimensions

Named presets keep request files readable and let the renderer/lint layer own the exact output contract.

The response still includes width and height so CI can verify the final file before upload.
