 Parametric plate, bowl and cup of the user's HOTEC wheat-straw dinnerware set (8 of each, four colours),
-version v3 (2026-10-29): v2 (the v1 geometry with the measured masses authored: plate 0.094625, bowl 0.067375,
-cup 0.0595 kg, 8-piece averages on a kitchen scale, 2026-09-22) plus the bowl's foot ring and height from the user's
-callipers (a vertical ring 65.72 mm outer diameter, 3.16 mm wide, 5.57 mm tall; the bowl 73.12 mm tall).
+version v4 (2026-10-29). It is v2 (the v1 geometry with the measured masses authored: plate 0.094625, bowl 0.067375,
+cup 0.0595 kg, 8-piece averages on a kitchen scale, 2026-09-22) with the bowl rebuilt from the user's callipers and
+depth readings: rim 144.53 mm outer diameter, 73.12 mm tall, a uniform 2.8 mm shell on the measured inner profile
+(domed underside, flat 2.8 mm rim top), and the foot ring a plain rib 65.72 mm outer diameter and 3.16 mm wide from
+the foot plane up into the shell. v3, earlier the same day, had the measured ring on the estimated body.

+edited here twice on 2026-10-29: v3 gave the bowl a vertical foot ring; v4 builds the bowl inner-first from the user's
+measurements (`BowlProfile`). The inner surface is a PCHIP z(r) through `profile_points` (the converted depth readings)
+and the rim edge, mirrored about the axis. The outer surface is that curve offset by the 2.8 mm wall along its normal,
+then a 0.9 mm straight step to the measured outer rim corner, so the rim top is flat and one wall wide. The foot ring is
+a plain rib from the foot plane up into the shell; its collision band is buried 1 mm in the shell. The plate and cup
+profiles are unchanged. Its sha256 `260b3aa0bed8b13f4c98f9d2da3f2e78ab5f5174cac2eb15123ecf8451957ed0` is the
