Great! Works fine as soon as you activate it

Nice to find a quick and simple way to make a site’s sticky header and logo shrink a bit when you start scrolling down the page, for block themes. Got used to doing it easily with page builders, couldn’t find a no-code way to do it in FSE. Hopefully this functionality will one day be a WP core option. Worked fine in the Twenty Twenty-Five theme as soon as I activated it, and there are controls to fine-tune the sizing if you want to.
