Reusable elements: build the header once
Delete the header from the page and drag the reusable one onto the root. If it lands inside a group, you did it wrong - check the element tree.
PROCEDURE: Reusable elements > Add new reusable element > name 'header' > type Row, left aligned, width 1440 -> copy the finished header group from index and paste it in -> back on index delete 'group header' -> drag 'header' from the reusable list onto the page -> 'Reveal in element tree' to confirm it sits directly under the page. One edit then updates every page. Same for footer and the property-card list ('properties' cloned from header to inherit width settings). The featured-section skeleton: Row with H3 + right-aligned 'Explore all' and ~40 px arrow icon, a filter Column of four category texts (bold 18, gap 24), padding 40.
