Neutral raking directional key (shadows) so facet creases shade and owned chassis read bone-white, cold fill and rim, desaturated ambient, HDR camera with TonyMcMapface tonemapping and LED-scale bloom (0.07 — NATURAL hazed the lit floor). Tester-only render change; no mesh, palette, or semantic edits. Defense: the visual identity makes lighting the mood carrier and emissive the information channel — the flat blue point-light rig was hiding both the facet geometry and the LED read. All scene lights stay neutral-to-cool per the no-warm-scene-light rule; amber remains exclusively machine presence. Documented in wiki/art/asset-tester.md in this commit.
