+// Letterbox — the cutscene frame.
+//
+// The one exception to the fixed layout. In cutscene mode the HUD strip and
+// the TopBar are hidden, the scene gets a black bar top and bottom, and a line
+// at the foot of the screen says a tape would like to speak — but it does not
+// speak on its own. The floor is the player's: a tape signals, never interrupts.
