Constant SHORT_SLEEP_NS 

const SHORT_SLEEP_NS: u64 = _; // 32_000_000u64

Short-sleep boost window. Periodic wakeup cadences such as the 60 Hz frame interval stay interactive. The per-task boost rate limit bounds the churn. The value is set against the slowest common cadence, so faster refresh rates, which sleep less per frame, fall inside the window as well.
