Good day!
We addressed this issue through the HTML code in description: https://bonndata.uni-bonn.de/dataverse/:root?q=

A more flexible and appealing landing page is of course desired nevertheless. I would also like at this point to mention my feature request that would allow for more general sub-collection branding: #10252

Good idea but I must admit that my first thought is that we should implement this in the new React frontend rather that JSF, which will someday go in the garbage. 🗑️
