Every row reserves the chevron slot, so artwork and titles share one column instead of stepping left when a feed has no children. Children keep a single icon size and read as nested from the indent alone. Labels stack on one line-height, and the unread count has a min-width so a three-digit feed doesn't shove its own title.
