{{-- Ported from sidebar.php (repo root) — see the Phase 4 plan. $role passed in
from layouts/app.blade.php (\App\Support\SessionAuth::role()). Pure
role-conditional nav markup, no query logic. --}}
{{-- bootstrap-icons and style.css are both linked once by layouts/app.blade.php
and layouts/partials/header.blade.php respectively. This partial only ever
renders inside that layout, so linking them again here just fetched the
same two files a second time on every page. --}}
