   FARM4GLASS — COURSE UNITS
   Loaded after style.css. Everything here is new: unit rows on the course
   page, the Video / Practice / Article tab bar, the PDF viewer, and the
   per-unit blocks in the admin course editor.

   Same variables, same fonts, same pill language as the rest of the portal.
