MIDNIGHTNAMEPLATES — PHASE 11.7.4
PREVIEW FINAL CALIBRATION

CHANGE
- Keeps the stable 11.7.3 optical-centering architecture.
- Moves the preview core cluster approximately 18px lower than 11.7.3.
- Preserves aura/name/health/cast relationships.
- Keeps only small bounded corrections for cast bars and bottom-anchored auras.

UNCHANGED
- Dynamic per-page scrollers from 11.7.1.
- Runtime nameplate behavior.
- Summon source/CVar safety architecture.

TEST
1. Enemy NPC + top auras + cast bar.
2. Compare empty space above aura rows vs below cast bar.
3. Auras OFF.
4. Cast bar OFF.
5. Friendly Player.
6. Friendly Pet Normal / Thin.
7. Enemy Pet / Guardian / Totem.
8. Verify all short/long page scrollers still stop at their own content end.
9. /reload: no Lua errors, taint, protected-action issues or FPS regression.

If this visual position is accepted, freeze preview positioning and continue to Phase 11.8.
