+   The layout knows which section you're in; only the page knows
+   which record is on screen. Rather than have both write
+   document.title and race — child effects run before parent
+   effects, so the layout would win and the record name would
+   never survive — the page publishes a string and the layout is
+   the single writer.
+
+   Null is the normal state. A page that publishes nothing, or one
+   still loading, simply leaves the section title showing.
