   CESIVI Modern UI — Shared page header + breadcrumb
   (ik "breadcrumbs always look ugly" bug, 2026-06-08)

   The .spm-page-header / .spm-page-title / .spm-breadcrumb convention
   is used on ~90 settings & _layouts pages (user.aspx, listedit.aspx,
   permissions, groups, fields, workflows, …) but had NO shared
   stylesheet rule — the only breadcrumb rule anywhere was the
   accessibility underline in _a11y.css. So the title rendered as a raw
   oversized <h1> and the breadcrumb as default-size text with raw
   ">" / "›" separators and default-blue links. That inconsistent,
   unstyled look is exactly the "breadcrumbs always look ugly"
   complaint.

   This gives the whole convention one consistent, token-based modern
   look, CSS-only (no markup churn across the ~90 pages):
     - breadcrumb pinned to the very TOP of the page content, above the
       title (SharePoint-modern convention), via flex reorder
     - breadcrumb small + muted, chevron-spaced, current page emphasised
     - page title a clean modern size/weight (not a giant default <h1>)
     - a subtle header underline so the block reads as one header
