Website sidebar now mirrors the App Center (sidebar.css): a 220px full-height
column, full-width category rows with bottom-border separators and the real
per-category icons (bundled into the site by the install hook from the live
frontend), and the same search box — instead of the rounded pills + generic
circles + count badges it had. Marketplace app copy shortened to peer style:
description 'App Catalog & Registry', one-sentence long description.
