+# Release assets use different architecture spellings: the .deb uses Debian
+# names (amd64/arm64) while the .rpm uses kernel names (x86_64/aarch64).
+# Keep the two maps separate so a single ansible_architecture value resolves
+# to the right token for each package type.
+# 'arm64' matches existing practice in roles/nvidia-dgx/vars/ubuntu-24.04.yml.
