Deep-linking into a low doc (e.g. ratings/get_ratings from the overview
page) opened the right menus but sat the highlight below the sidebar's
visible scroll area. scrollSidebarToActive() runs at docs Alpine init:
finds the link for the current path, and if it's outside the sidebar's
scrollport, moves ONLY the sidebar's own scrollTop to clamp it into the
nearest edge — never the page scroll. Skips the off-canvas mobile
drawer. (Same behavior as Docusaurus/MkDocs on deep links.)
