feat(hero): stepped medallion relief, seated on the parapet face

The medallions were not just flat - they were buried. seat_on_front put
Hero_Medallion at offset 0.08 (front Y -0.42) while the 1.2 m-deep parapet stands
at Y -0.15, so both discs sat inside the parapet and never rendered. The motto
band and surround have the same burial (offset 0.06) and are a separate follow-up.

- Three stepped layers per medallion with per-layer prefixes so seat_on_front gives
  each its own stand-off: Rim (0.55 m, dark, offset 0.36 -> Y -0.14), Field
  (0.38 m, light, offset 0.43 -> Y -0.07), Boss (0.15 m, dark, offset 0.50 -> Y 0.00).
  A single Hero_Medallion prefix would both flatten the relief and (via startswith)
  swallow the specific prefixes, so it is removed.
- Moved from +/-6.2 (inside the inscription text, which spans +/-6.87) to +/-9.8.
- Fixed Tools/review/hero_iterate.sh, which still had the pre-tools-move
  'cd dirname/..' and landed in Tools/ instead of the repo root.

Rendered and judged; the advisory two-model judge (no, 0.93) no longer flags the
medallions. Owner review pending.

 ## 2026-11-10 — Render-to-import chain, in one order
 
 A visual change needs **build → import → render**, never just a render: `render_screenshots.sh` renders the imported Unreal assets. `Tools/review/e2e_asset_check.py` runs the whole thing (Blender renders → empty maps → both builds → captures → two-model judge → README) and is the command to use instead of remembering four.

+## 2026-11-10 — Hero attic: the medallions were buried, not just flat
+
+- **`seat_on_front` offsets are relative to `FRONT_Y` (the wall plane, Y −0.5), not to the parapet face.** The parapet is 1.2 m deep with its front at Y −0.15, so any applied detail with offset < 0.35 sits *inside* the parapet and never renders. The medallions (offset 0.08 → front −0.42) and the motto band + surround (offset 0.06 → front −0.44) were all buried; only the inscription (moved to 0.40 → front −0.10 in the previous commit) read.
+- **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.
+- **Medallions were also at ±6.2, inside the inscription text (spans ±6.87).** Moved to ±9.8.
+- **`Tools/review/hero_iterate.sh` still had the pre-move `cd "$(dirname "$0")/.."`** from the tools restructure — it landed in `Tools/` and failed `find Art` with "no such file". Fixed to `../..`, matching `render_screenshots.sh`.

 - [x] **Make the generated ashlar albedo render.** Two blockers, both measured: the map's generic material pass was **overriding every hero slot** with the kit's flat stone (`comp.set_material` on `Hero_Facade`), and assigning authored materials to the _mesh's_ slot list does not persist because `get_editor_property("static_materials")` returns a copy. What works: exclude the hero from the generic pass and set **component-level overrides** to the authored `*_Ref` materials in both builders (`apply_hero_materials()`). The elevation now shows coursed, grainy limestone.
 - [x] Carved inscription: `inscription()` in `Tools/blender/hero_facade_build.py` lays 112 letter marks in three lines across the attic, in the shadow stone so they read at 45 m. They had to be **seated on the parapet face** (`FRONT_Y + 0.40`): the parapet is 1.2 m deep and stands in front of the wall plane, so marks at the wall plane were hidden behind it.
-- [ ] Medallion relief that reads at 45 m - the two discs exist but are flush and empty; a bevelled rim and a raised motif would read, or a baked texture.
+- [x] Medallion relief that reads at 45 m. **Measured first, then fixed:** the discs were not just flat - they were **buried**. `seat_on_front` put `Hero_Medallion` at offset 0.08 → front face Y −0.42, while the parapet (1.2 m deep) stands at Y −0.15, so both medallions were inside the parapet and never rendered (the motto band and surround have the same bug at offset 0.06). Fixed: three stepped layers per medallion — `Hero_MedallionRim` (0.55 m, dark, offset 0.36 → Y −0.14), `Hero_MedallionField` (0.38 m, light, offset 0.43 → Y −0.07), `Hero_MedallionBoss` (0.15 m, dark, offset 0.50 → Y 0.00) — a 7 cm step each way so the rim/field/boss read as relief. Moved from ±6.2 (inside the inscription text, ±6.87) to ±9.8. Rendered and judged; the two-model judge is advisory-pessimistic (`no` 0.93) and does not flag medallions any more. Owner review pending.
 - [ ] Banner lettering (JIMMY KIMMEL LIVE) - needs a texture; the banners are flat panels today.
 - [ ] Crimson banner tone and the JIMMY KIMMEL LIVE lettering.
