{# Breadcrumb trail from section root down to current page.
   Walks page.parent_id via the page_ancestors Jinja global (SQL-backed,
   bragi's Page model has no .parent attribute). Each crumb's URL is
   produced by url_for_page. ► separators between items.

   Site title is NOT prepended (the top bar already shows the brand
   linking to /). Single-item trails (current page IS the section
   root) are suppressed entirely — at that point the breadcrumb would
   just repeat the H1 below it, adding visual noise without
   navigational value. #}
