- DisplayManager.defer_update()/process_deferred_updates(): one lock around every queue mutation (appends from the update thread were lost to the render thread's filter/slice reassignments); callables run outside it. - FontManager and element_style no longer cache BDF freetype.Face objects process-wide (load_bdf_face caches them per thread); element_style's LRU is locked against get/move_to_end vs eviction races. - limit_refresh_rate_hz default is one constant, DEFAULT_REFRESH_LIMIT_HZ = 100 (the template's), for the library options, refresh_hz, the matrix guard, Vegas and scroll_config. Previously a missing key capped the panel at 90 while pacing assumed 100. - Sync follower: the TCP thread queues the leader's scroll image; the render thread swaps image/array/width in between frames. - update_display() error log rate-limited (traceback first, then once a minute with a count); swallowed DisplayController exceptions log at DEBUG. - Root display_controller.py runs run.py via runpy. - stream_manager: correct the RLock release comments; merge duplicate if.
