+# Updates the bundled CEM entity-model set (the only asset PixelPics vendors itself).
+#
+# Source: the CEM Template Loader data (Ewan Howell / wynem) — vanilla Java entity models as JSON,
+# already correctly posed. These ultimately mirror Mojang's hardcoded Java EntityModel classes.
+#
+# Most future-proof alternative for a NEW Minecraft version (sourced straight from the game):
+#   1. Install the JsonEM mod (Fabric), set dump_models=true in .minecraft/config/jsonem.properties
+#   2. Launch the game once -> models dumped to .minecraft/jsonem_dump
+#   (a small format-adapter would be needed; the CEM source below covers vanilla until then.)
+#
+# Usage:  tools/update-cem-models.sh           # update if newer
+#         tools/update-cem-models.sh --force   # always overwrite
