# Shared HuggingFace cache for all three engines.

# ReadWriteOnce is correct here despite six pods mounting it: RWO means "one
# NODE", and every pod in this app is pinned to worker-1 via nodeSelector, so
# they share the volume legally. If a pod is ever allowed onto another node,
# this must become RWX first.
#
# StorageClass is longhorn-llm-local (1 replica, strict-local, disk tag `llm`)
# — NOT the default 3-replica class, which could not place this volume at all:
# every control-plane disk was already at its over-provisioning ceiling.
