   Guides — the twenty worldwide topic hubs and their index.
   Loaded per-page by scripts/theme_v2/build_guides.py, not
   imported into theme.css (see theme.css's header).

   The hard problem here is density: a topic page carries up to
   ~620 destination links. Grouping them by country and setting
   the groups in columns keeps the page scannable instead of
   presenting one enormous undifferentiated list.
