    // is a hard `alpha < 0.5 ? 0 : 1` step, which throws away the one thing
    // that makes the cut look drawn rather than pixelated: the mask Shape's own
    // coverage antialiasing. Every partially covered pixel along a diagonal got
    // rounded to all-or-nothing and the art came out with a visible staircase
    // down both leaning edges. A narrow spread lets that single-pixel ramp
    // through and nothing wider — still a cut, just not a jagged one.
