 3// A thread large enough to exceed the foreign-block render budget
 4// degrades gracefully: rendering stops before gnoweb's per-render
 5// foreign-block cap would blank comments, and a "More replies — view
 6// full thread" notice is shown instead (see maxRenderedBodies). The
 7// reply count and assertion are derived from MaxBlocksPerRender so this
 8// stays a truncation test if the cap changes.
