Collapse the three nav builders into buildPluginChrome: chrome.bestHref does longest-prefix matching so deep admin routes mark their leaf. Delete adminNav; buildConfirmModel and the admin model builders take the resolved nav. The same role-filtered sidebar now renders signed in or out, collapsing to a burger on narrow screens.
shell.ejs gains menu (default true; menu:false -> single-column .app-bare), docTitle (separate <title> from the topbar, so the body keeps the single <h1>), and hideSignIn (suppress the footer Sign-in on auth pages to avoid a login loop). auth/home/landing now render inside the shell.
Dashboard is a replaceable instructional starter (definePlugin snippet, no mock data). Email stays delegated to Kratos: documented its built-in courier.template_override_path instead of adding web-side SMTP.
