+with exact French labels and units, dense numerical scales, restrained patina,
+and green, amber and red operating sectors. The generated needles, bezels and
+glass were explicitly excluded because those parts are modeled and animated in
+Godot. The source outputs were resized to 1024 × 1024 and given a circular alpha
+mask for flat, distortion-free mounting inside the physical bezels.
