   PAGE-HEADER STRIP (.canvas-toolbar) — Sprint 3 §3.3
   The decision per Sprint 3 audit: stay page-driven. Existing
   page-loaders write into `.toolbar-title` (page title) and
   `.toolbar-breadcrumb` (eyebrow). Those selectors keep working;
   they get the new visual treatment in place.

   New canonical slot names live alongside as aliases so future
   pages can target `.cf-page-header__title` / `__eyebrow` /
   `__actions` directly. Rename happens on per-page touch in
   Sprints 4–7.

   Layout: eyebrow (top, small, tracked caps with ::before square)
   + page title (below, larger, ink) + right-aligned actions slot.
