+/**
+ * Details panel layout for UNpcScheduleAsset: everything the asset already had, with the day its
+ * actions describe drawn underneath it as a strip, see SNpcScheduleTimeline.
+ *
+ * All this does is put the strip there. It adds no row for any property and takes none away, so the
+ * actions themselves keep the rows the panel and FNpcScheduleActionCustomization give them: the strip
+ * is a view of what those rows say, and a second place to write an action would be a second answer to
+ * what a day is.
+ *
+ * The strip goes in a category of its own sorted after the one the asset's properties land in, which
+ * is what puts it at the bottom of the editor. A category is as close as a details customization can
+ * get to the bottom of anything: the panel is one scrolling column and everything in it is a row of
+ * it, so the bottom of the panel is the bottom of the layout, under every row rather than pinned to
+ * the edge of the window the way a status bar would be.
