Beamer presentation using Maschinenbau corporate design

Hey, I remember a few years back (in 2021 if I remember correctly) I was able to create presentations in the Maschinenbau corporate design (Blue and yellow with a large horizontal vector in the bottom of the page) using the tuda-ci package. There was also an explanation in the tutorial pdf back then, it was quite straightforward, I remember. Now, in 2025, I want to create new beamer presentations using that layout, the explaination seems to have left the tutorial and if I recompile my old code again, it doesn't look the same anymore. It doesn't match the MB corporate layout anymore (still kind of, but clear differences now), and functions like the choice of background color seem to be lost. Is the Maschinenbau layout still officially supported in the TU Darmstadt LaTeX? If so, how does it work now? :) Thank you for your help! Best regards, Jakob
