"""run_iteration() does no per-iteration static-mode bookkeeping.

Every iteration used to rebuild a set of STATIC-mode plugins -- asking each
plugin for its display mode and logging the result at INFO -- that nothing
ever read. The static pause is driven by _check_static_plugin_trigger(), which
looks at the next segment, not at that set.
