Section navigation
Keep orientation within a department or section when the legacy page tree is still required.
The legacy example shows nested page links. The FYE Secondary header example shows an introduction and action, without that tree. Its curated navigation option does not establish automatic ancestor/sibling/child behavior.
A static preview cannot prove tree generation. The need also follows the source Sidebar Nav Settings fields. A curated header menu is sufficient if automatic hierarchy is deliberately retired.
Proposed structure
Concept only — this describes the suggested addition; it is not an implemented destination component.
Ready when: Changing page hierarchy updates the navigation; current-page state and direct child links work on desktop and mobile.
