Day 8 disk-cache warmer crashes on production with
'Read-only file system : /home/app/data' because the relative default
'data/voice-previews' resolves under runAsNonRoot HOME (read-only with
readOnlyRootFilesystem=true). Pin to /data/voice-previews so the cache
lands on the writable PVC mount alongside ttsreader.db, audio output,
and jobs root.
Image v202604272216 (already on nodes) is unaffected by this — only
the env routing changes. ArgoCD reconciles + rollout restart picks up
the new env without rebuild.
