Band in demo looks different from prod

[marionnegp]

Heading text should be smaller (25.2px) and lighter (400).

Benny commented:

In this case, those look like light DOM styles applied by the consuming page.

• [ ] We should rewrite the demo to slot the h2 and p directly into the header slot, where we can specify the weights etc. Like above, this was a preexisting issue and we should deal with it separately.

Also, a 16px space should be added above the CTA in the default band, darker band, and dark band with bg image. I think this is pulled in as a margin-bottom for the last body paragraph.
