/* ==========================================================================
   Higher Ed Futures
   A register of institution-level evidence.

   Design notes
   - Jurisdiction is the spine of this content, so it is a structural column,
     not a decoration. Every record carries it in a sticky left rail.
   - Monospace is reserved for record data: jurisdictions, sources, dates,
     counts, navigation. Serif is reserved for argument. Nothing crosses over.
   - No entry numbering. The registers are lists, not sequences; numbering
     would imply an order that is not in the evidence.
