+Blender 5.1 script: render preview frames of matador animations to PNG.
+Run:  blender --background matador_v02.blend --python render_anim_preview.py
+
+Outputs to Blender/preview/ directory:
+  walk_frame_00.png .. walk_frame_09.png
+  idle_frame_00.png
+
+Use this to visually verify bone orientations BEFORE exporting to Godot.
