+"""Build the vanilla entity-texture index for the model viewer.
+
+Scans ``MEDIA_ROOT/vanilla/entity/`` (extracted from a Minecraft client jar)
+and writes ``MEDIA_ROOT/vanilla/entity_index.json`` mapping each entity name to
+the best "base skin" relative path, so the renderer can fall back to real
+vanilla textures for models that have no pack textures of their own.
