{% comment %} Switcher across the sync rule/pattern object lists (the sidebar has ONE "Rules & Patterns" entry). Same contract as _mapping_tabs.html: plain page links above the native Results/Filters tabs, with the active pill also carrying aria-current="page". Navigation tests assert its class, href, and aria-current attributes independently. A branch that introduces a new rule or pattern model adds its tab here (and to RULE_LIST_ROUTES in the navigation tests) in the same commit that adds the model. {% endcomment %}
