Marketing mobile-nav toggle (icvoss/django-brickwork#263).

Package-owned companion to marketing_nav_region: a native <details>/<summary>
disclosure that, as a SIBLING of .bw-marketing-header__nav and
.bw-marketing-header__actions, collapses those regions on narrow viewports
and reveals them when open. marketing.css owns the collapse rules; this
partial owns only the trigger markup.

Place it by overriding marketing_nav_region (do NOT fill the outer
marketing_header and reproduce the shell):

  {% block marketing_nav_region %}
    {% include "brickwork_marketing/components/_mobile_nav_toggle.html" %}
    <nav class="bw-marketing-header__nav" aria-label="{% translate 'Primary' %}">
      {% block marketing_nav %}...{% endblock %}
    </nav>
  {% endblock %}

Or insert it before marketing_actions_region the same way. Sibling position
is load-bearing: the CSS uses general sibling combinators off
.bw-mobile-nav-toggle[open].

No JS (BR-BW-HTMX-001). Both icons always render; CSS toggles which shows on
[open]. Accessible name is on <summary> (aria-label); icons are decorative.

States: closed (default) and open (native details[open]). CSS swaps the
  menu/close icons and reveals following nav/actions siblings when open.
Accessibility: summary carries aria-label="Menu"; icons are decorative
  (decorative=True). Closed, the following nav/actions are display:none
  (removed from the a11y tree) until the disclosure opens. No Alpine.
Responsive: marketing.css shows the toggle below --bw-breakpoint-lg (64rem)
  and hides it at that breakpoint and up, restoring the inline nav/actions
  bar.
