Research direction
Investigate the image rendering code in react pdf, likely in the Image component (src/elements/Image.js or similar). Check if the library reads EXIF orientation metadata. Consider using a library like exif js or the browser's built in orientation support. Test with the provided image file and ensure the output PDF matches the expected orientation.
