{% load i18n brickwork_icons %}
{% comment %}
Recursive nav render (NAV-016: one render shared by desktop sidebar + mobile
drawer). Uses Django 6.0 {% partialdef %} for the recursive item partial;
brickwork is the first umbrella package to use the 6.0 template partials, so
there is no django-cotton / django-render-block here (BR-BW-TPL-003/004).

Items arrive already prepared by {% bw_nav %} (URL resolved via safe_reverse,
active/ancestor-active state and the disabled/external flags computed), so this
template is pure presentation: no {% url %} that could 500 (BR-BW-NAV-003), no
permission logic (visibility was filtered upstream).
