Hi there,
I ran into the same issue while working on mail order brides guide using Signify Blocks Pro. The homepage was locked to full-width, which clashed with my boxed inner pages.

What worked for me was creating a child theme and applying a custom class to the homepage container. I also adjusted some CSS to mimic the boxed layout used on other templates. It’s not ideal out-of-the-box, but it gave me consistent visual flow across the site.

If anyone needs a sample CSS snippet or layout file, happy to share.

Best regards,
Travis Smith
