How it is built
Cells merge into one outline, then every convex corner bends on a curve of up to one cell. A one-cell stroke end gets two half-cell curves, which makes a round cap.
Concave corners stay sharp, so a bend keeps the stroke's width like a bent glass tube. B, D, E, F, P and R keep a flat back, which is what tells D from O.
One cell is the font size divided by eight, so at 16, 32, 48, 72 and 120 px every edge lands on a whole pixel. The tester and the waterfall only offer those sizes.
