 ### Storage Classes
 
-Default storage class used: **UpCloud default** (varies by provider)
+Storage classes are cloud-specific and configured in per-cluster value overrides (`infra/values/{cluster}/gitea-values.yaml`):

+| Cloud | Storage Class | Driver |
+|-------|--------------|--------|
+| **UpCloud** | `upcloud-block-storage-maxiops` | UpCloud CSI |

-  storageClass: ""     # Uses default
