	78	+ * Renders the orientation header for the chromeless Themes workspace.
	79	+ *
	80	+ * Core's page heading is intentionally hidden inside OpenStation because the
	81	+ * window chrome already names the screen. The Themes page still needs a little
	82	+ * more context than a generic list screen, though: a theme changes the public
	83	+ * face of the site, and Core's single-theme state otherwise opens directly on
	84	+ * an unexplained details panel.
	85	+ *
	86	+ * The markup is emitted through `admin_notices`, which places it immediately
	87	+ * before the page's `.wrap`. Core continues to own the theme cards, details
	88	+ * overlay, actions, AJAX updates, and keyboard behavior.
	89	+ *
	90	+ * The screen is identified by `get_current_screen()`, not `$pagenow`. Every
	91	+ * page registered with `add_theme_page()` also reports `themes.php` as its
	92	+ * `$pagenow`, but its body class comes from the hook suffix
	93	+ * (`appearance_page_<slug>`) and so matches none of the workspace CSS, which
	94	+ * is scoped to `.themes-php`. Gating on `$pagenow` would emit this header
	95	+ * unstyled on top of unrelated Appearance screens. The screen ID also keeps
	96	+ * network admin (`themes-network`, a different list table entirely) out.
