{{/* Page anatomy: the page header (docs/design-system.md §6; spec
     page-anatomy "One title size and one header layout"). Pipeline:
     server.PageHeader. The only template that renders an <h1>: one size
     (h1.h2), an optional location trail above it (chrome-conventions
     "One location trail": a Bootstrap breadcrumb rooted at the surface,
     the per-template-set surfaceRoot function first, then .Crumbs, then
     the current page appended as the unlinked aria-current crumb; the
     surface's own root page (PageHeader.NoTrail) carries none; design
     D18), an optional one-sentence lead below it, and one right-hand slot
     holding a muted count or one action control. Check() aborts the
     render when a page supplies both. Parsed into every set by
     web.ParseUIPartials. */}}
