   Engagement writing coach: the layer over a ReLeaf page
   -----------------------------------------------------------------------------
   Highlights in the students' text, note cards in a right-hand margin on wide
   screens (a bottom sheet on narrow ones), a summary card under the page head,
   and a frosted toolbar floating at the bottom of the window. Everything is
   prefixed .cx- so nothing here touches the page's own classes.
