+- The stated body height is now **0.260 m** (`BODY_H`, was 0.180). The
+  face block is 75 mm thick, and the outer AABB z was refitted from 0.489

+- The body is one superellipse loft of eight rings. It starts at a broad
+  foot (0.250 × 0.164 m, as large as fits inside the stump's chime),
+  pinches below mid-height, and swells along the face's length into its
+  underside. The heel's underside rises 30 mm toward its end.
+- The horn is round-sectioned and about as wide as the table at its root.
+  Its top runs on from the table, and its belly is deep enough to sweep
+  into the throat. It has six rings, fewer than the body's eight, so the
+  waist-form audit still finds the waist.
+- The face block and table chamfer their corners. Hole mouths stay sharp.
+- The polished face is a satin sheen (roughness 0.30). At 0.16 it was a

+- The staves are weathered oak. The hammer is lofted: a chamfered face, a
