   Home columns: the sections of home.section beside the narrower column of
   home.aside. public/index.html only renders this markup when some feature
   contributes to home.aside, so a home without an aside never matches these
   rules. Loaded via the asset registry (register_asset in init_feature).

   A skin or product changes the split with --home-columns, for example
   `.home-columns { --home-columns: minmax(0, 1fr) 20rem; }`.
