   TRANSFER - a city journal arranged as a transit network
   ---------------------------------------------------------------------
   Design notes:
   - Radius system (documented mixed rule): structural surfaces use a
     near-sharp 2px radius (civic signage). Route nodes are full circles
     because they are station markers, not containers.
   - Color system: ONE interaction accent ("signal") per theme, plus a
     semantic transit-line palette mapped to the five categories.
