/* =========================================================================
   MAESTROX — Unified Page Header
   One pattern that handles every page in the portal.

   Anatomy (all parts optional except title):
     ┌─ Breadcrumb ─────────────────────────────────────────────────┐
     │ [Tile]  Title                                      [Actions] │
     │         Meta / role / stats line                             │
     │         Description                                          │
     └──────────────────────────────────────────────────────────────┘
     [Sub-row: tabs · filters · search · view toggle] (attached if present)

   Designed against the gold canvas. Content sits directly on canvas —
   no card chrome — but the optional sub-row uses a working-surface band
   that visually anchors the page below.
