/* ── Shared page banner ─────────────────────────────────────────────────
   The brown gradient header used across the tool pages. Twenty-one templates
   carried their own identical copy of this; it lives here now so the pages
   that use includes/page_header.html need no CSS of their own. The existing
   inline copies still work and simply override with the same values. */
