+# Merge Mixamo FBX files (1 character + N animations, same rig family) into a
+# single GLB with all the clips, ready for DJ Visualizer's dance director.
+#
+#   blender -b -P scripts/merge-mixamo.py -- <base.fbx> <anim1.fbx> ... <out.glb>
+#
+# - the base FBX provides the character (mesh+skin); its embedded diffuse
+#   texture is recovered when the FBX references missing external files
+# - animation FBX files only contribute their action (objects are discarded)
+# - bone-name prefixes are retargeted (mixamorig / mixamorig1 / ...) so clips
+#   recorded for another character land on this rig's bones
