+<!-- The gram sits outside the reading column on purpose. The column is 1100px
+     wide so the notes read comfortably, but a component that narrow is not
+     what an analyst's page gives it: the control row collapses its guidance
+     and squeezes the annotation tables below about 1180px, and the picture
+     itself loses half the width a full-page gram has. Full width is what the
+     trial is meant to show. -->
