{# _sidebar_nav.html — nav items rendered inside _app_shell's
   <aside class="wf-sidebar"><nav class="wf-nav-list">.

   Required context:
     - shell.nav_items : list of { href, label, group: "admin"|"account", active: bool }
   Items arrive pre-ordered: admin entries first, account entries last.
   Groups render under .wf-nav-section headers; items use .wf-nav-item + .is-active.
   Renders nothing if `shell` is undefined (lets legacy pages without shell render cleanly).
