The tabs were drawn in each page's content block, which base.html renders after the breadcrumb, so on every nested Ansible page the strip moved down a line. base.html now has a section_tabs block above the breadcrumb, and every Ansible page fills it. A guard in test_breadcrumbs.py fails any page that calls a tabs macro outside that block. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
