"""Door robot arm, red look (2026-10-19): apply the look inside a live Blender (the user's open arm file, or the ship
with version B installed), through the MCP: exec this file's text. Well under a minute (about a second: the texture
bands come from build/surf_ranges.json, the baked maps load lazily).

What it changes, and nothing else:
  * renames M_DoorArm_PaintWhite -> M_DoorArm_PaintRed, M_DoorArm_Orange -> M_DoorArm_Marking and
    M_DoorArmKit_Orange -> M_DoorArmKit_Marking where only the old name exists (slots follow the datablock);
  * rebuilds the node trees of the M_DoorArm_* and M_DoorArmKit_* materials that exist, from dra_surf's recipes;
  * loads textures/T_DoorArm_Masks.png and T_DoorArm_BevelNormal.png (or reloads them if the file has them), by a
    path relative to the open file (in the ship: //door-robot-arm/textures/...).
No slot, mesh, curve, object or other material is touched. The result is the dict `result`.
