Wire built-in admin screens into the global menu (todo §5); extract adminSection() = one permission-gated 'Admin' header (Users/Groups/Roles), reused by both the home dashboard menu and the in-screen adminNav so they can't drift. composeNav drops the whole gated header+subtree for a non-admin/anonymous (cosmetic — the admin routes stay independently GuardError(403)-gated); narrowed AdminScreen to groups|roles|users. Reuses existing sprite icons (no icon-guard change); default anonymous / render byte-equivalent so visual E2E unaffected. Tests-first: dashboard model gating (admin→3 hrefs, non-admin→absent) + app HTTP (admin JWT→/admin/users link, anon→absent). Stability-reviewer run as a local PR: APPROVE, no Critical/High/Medium. README Layout updated. 242→244 units + typecheck green
