+- BREAKING: `shrink_wrap` traces the rolling ball exactly — pivoting it around
+  the cloud and offsetting the polygon through the points it touches
+  (`pivot_contour`) — instead of thresholding and marching-squares-tracing a
+  distance field, so there is no grid resolution left to set. `ShrinkWrap`'s
+  `cell_size` is accordingly named `min_clearance`, still accepted under the old
+  name, and floors `clearance` only for an open single-membrane cloud; a closed
+  loop keeps its true `clearance`, so `clearance=0` hugs the input and leaves
+  its sharp trailing edge sharp. The wrap sits at exactly `clearance` from the
+  cloud instead of a cell over it, so a V3 canopy's aft strip comes out
+  `2 * clearance` thick where the grid gave `3.5 * cell_size`.
+  `min_concave_radius` stops costing anything, having padded the grid in both
+  directions before: one V3 slice at radius 0.4 drops from 173 ms to 10 ms, and
+  at the default radius from 15 ms to 3 ms.
