How it works
The tachometer is the burn rate of the side Justin is on, the same pace as minime's: the share of the window's time left over the share of its usage left, the worse of the 5-hour and weekly windows. 1× uses it up exactly as the window resets; above 1× it runs out early. The needle catches fire past 1.5×.
The shift indicator shows where the usage is going: each check compares how much Engineering and Company grew since the last one, and the knob slides toward the split (a little for a small change, most of the way for a big one). When neither grew, it stays put, so it still shows which side Justin is on.
The shift light is meant to be rare. It comes on only when the side in use reaches 95% of its 5-hour or weekly limit (or hits the limit) and the other side is under 95% on both. It notifies once per shift. If both are that high, it says ease off instead. Usage is checked every 2 minutes.
