How to hide website title in quarto when using a title-block-banner?

Question

I use a simple setup of a quarto website in R. The code is on GitHub https://github.com/EUV-student/history The site is on GitHub Pages https://euv-student.github.io/history/ I use a title-block-banner. The website title overlays the banner and is unreadable and redundant, since I can see the title in the navigation bar. How can I get rid of the midway website title?

For completeness, my _quarto.yml is:
