Bug description

When attaching this image to any recipe, it gets rotated 90 degrees to the left. But not for the small preview.

The metadata contain the Orientation tag which seems to be honored by the preview, but not by the downsampling operation.

$ exiftool 20260801_175525.jpg | grep Orientation
Orientation                     : Rotate 90 CW

Preview:

Final:

Contributor guide

Research direction
Investigate the image processing code to find where downsampling occurs. Check if EXIF orientation metadata is being read and applied, and compare with the preview generation path to identify the missing step.
