"""Shared, thread/async-safe screen context.

|
|
The perception loop keeps writing the latest ScreenObservation here; the
|
|
conversation loop reads it when the user says something. We only keep the most
|
|
recent observation plus a short ring buffer of recent ones so the Brain can
|
|
notice "the screen changed" without us re-sending every frame.
