/atom/movable/screen/map_view/examine_panel_screen/runtime_lifetimes	Records whether each viewer released the real screen before it was destroyed.
/datum/unit_test/meridian_modular_persistence	Uses synthetic accounts in isolated files; never reads or replaces existing player data.
/atom/movable/screen/map_view/char_preview/runtime_lifetimes	Counts requests at the real preview rebuild boundary, without needing a browser or client during teardown.
/datum/preference_middleware/character_preview/runtime_lifetimes	Provides only the browser and iconforge boundaries; all queue, session, drawing, and publication logic is real.
