I’d just be cautious about joining the two strings with \n — that approach turns them into a single text block, which can cause issues later on with dynamic type, truncation.

I’d recommend rendering them as two separate Text views inside a VStack instead. That gives us better layout flexibility.

Also the the current spacing in the header seems to be off compared to the design of i2.

The spacing is also 2 above "Women's Haircut" i just could not take the sceenshot with that.

@AdamGrzybkowski Good observation! I separated the labels as suggested in d5c7f92 - this PR is ready for another look 🙏
