A per-page header component (breadcrumbs, title, actions) rendered inside the main content area instead of a global header, keeping page-specific chrome scoped and safe against XSS.
When to use: Reach for it when a page needs a title, breadcrumbs, or action buttons without adding a site-wide header.
