With ghostscript, how to upscale a PDF file that is wider than taller so that the new width matches the width of a portrait A4 sheet of paper?

Let's take a PDF file that is slightly wider than taller, e.g., https://we.tl/t-iihJ3gMsrA : pdfinfo input.pdf | grep "Page size" Page size: 397.349 x 378.153 pts Let's try to upscale it so that the new width matches that of a portrait A4 sheet, i.e., 210 mm or 595 pt. How to do this with gs only? So far, we tried gs -o output.pdf -sDEVICE=pdfwrite -dFIXEDMEDIA -dPDFFitPage -dAutoRotatePages=/None -dDEVICEWIDTH=5950 -dCompatibilityLevel=1.4 -dNOPAUSE -dBATCH input.pdf and variations thereof, but the output came out rotated counterclockwise 90° :-(. Any adjustment to the command so that the output comes out upright?
