	// TickIdle is used when the player is stopped or paused with nothing
	// animating (no overlay, no buffering, no pending status / reconnect).
	// Bubbletea wakes immediately on key / IPC / MPRIS / plugin messages, so
	// the tick at this cadence only services time-based self-changes
	// (status-message expiry, log-line aging) — those tolerate the latency.
	TickIdle = 1500 * time.Millisecond // ~0.7 Hz — fully idle, minimal CPU
