fix(hero): seat the motto band and surround on the parapet face

The motto band and moulded surround had the same burial as the medallions: offset
0.06 left their front face at Y -0.44, inside the 1.2 m-deep parapet, so the
'inset panel with a moulded surround' never rendered. Only the inscription (moved
to 0.40 in the previous commit) read.

- Band recessed at offset 0.34 (Y -0.16), surround proud at 0.43 (Y -0.07),
  inscription stays 0.40 (Y -0.10).
- Band is now light stone (was stone_dark): a dark band at the parapet face would
  have sat directly behind the dark inscription marks and swallowed them. The
  reference is dark incised lettering on a pale band.
- Removed the dead duplicate 'Hero_MottoBand 0.40' entry - the earlier 0.06 match
  won, so the 0.40 was silently ignored.

Rendered and judged; the advisory judge no longer flags the band.

 - **Medallion fix:** stepped relief with per-layer prefixes so `seat_on_front` gives each its own stand-off — `MedallionRim` 0.36, `MedallionField` 0.43, `MedallionBoss` 0.50. One shared prefix (`Hero_Medallion`) would seat every disc at the same offset and flatten the relief, and it also matched the more specific prefixes via `startswith`, so it had to be removed entirely.

+## 2026-11-10 — Hero motto band + surround: same burial, plus dark-on-dark
+
+- The motto band and moulded surround shared the medallion burial (offset 0.06 → front
+  Y −0.44, inside the parapet). Fixed the same way: band recessed at 0.34 (Y −0.16),
+  surround proud at 0.43 (Y −0.07), inscription stays 0.40 (Y −0.10).
+- **The band had to go light (`stone`, was `stone_dark`) at the same time.** A dark
+  band at the parapet face would have sat directly behind the dark inscription marks and
+  swallowed them; the reference is dark incised lettering on a pale stone band.
+- **The `seat_on_front` table had a dead duplicate** — `Hero_MottoBand` appeared at both
+  0.06 and 0.40, and the first match (0.06) won, so the 0.40 was silently ignored. That
+  is why "the band is buried" looked fixed in the table while the build kept burying it.
