// PKGPATH: gno.land/r/gnoland/boards2/v1/filetests/z_ui_thread_08_filetest

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