Order summary component with vanilla CSS

I'm definitely getting more comfortable with the layouts! Two questions I need help with please:

1. How do I create the background with the curves?

2. Is there a better way to handle the image border radius? I feel I'm duplicating the rounding on the image but it doesn't inherit the shape from the container and overflow: hidden; doesn't seem to make a difference.

Any other feedback to make my code better would be highly valued!

Thank you! Kate
