How can I change the font of my product card title?

Dear Community,

I can’t seem to find the right spot in the code so I come to you for your help. As you can see in the screenshot, the title of the product has a different font than the producer or the ATC (it has the font for headings all over the shop). And I would like to have it the same font as the producer (the font for all other text in the shop).

Can you give me a hint where and how to change that?

Thanks a lot and best regards!
