 The Bookmarks widget keeps direct URLs and Homarr Apps in one ordered list. URLs do not require an App record; Homarr
 uses the site's favicon when available. Choose adaptive, compact-grid, or other layouts from the widget configuration.
+Adaptive, vertical, and grid layouts keep larger cards when the configured bookmarks fit, then reduce card height and
+spacing to show as many bookmarks as possible before scrolling. Horizontal uses a compact, centered scrolling row with
+narrower cards in one-row widgets. Horizontal, compact-grid, and icon-only layouts keep their gaps tight. Compact grid
+also preserves its configured columns when the dashboard is scaled.
