The team expressed some concerns about the border that should appear on mobile. It might require some changes at the inner cart level, so there is a high chance we might not be following that design if the solution is not straightforward: low effort, no impact on blocks's structure

Nikki and I discussed this today and we are going to increase the padding to 48px rather than 40px.

We also noticed the following issues that need to be solved:

1. The spacing underneath the terms and conditions block should be increased in case that block is moved. Currently there is no space under it.
2. The separator between the order notes block and terms and conditions block should be removed and in its place an independent separator block should be added.
   1. This block should be styled like the existing one, in light grey.
   2. The default separator block should not be affected by this.
   3. The merchant should be able to move/remove the order notes, checkout terms and conditions, and separator.

Next steps for this issue are to address point 1 above in #47565 and for @nikkivias to review

Create a follow-up issue for point 2 as it would add complexity to the existing PR.

Follow up issue is created: #47910

Update to the above comment, we will add a separator to the checkout terms block and add an option to disable it in case the block is moved. The issue to track this change is here: #47910
