   coursematter — legal pages (Views/Policy/*, layout Views/Shared/_CmxDocLayout)
   Loaded after co-home.css and uses its tokens, top bar and footer.
   Everything is scoped under .cmx-doc.

   The idea: the fine print, set like a well-made book. A quiet hero with a
   big serif section mark, an "at a glance" card, then a reading column
   with a sticky index that tracks where you are. No loud motion — the only
   moving thing is the thin progress line under the top bar.
