+Usage: showcase logs <slug> [options]
+
+Follow container logs with optional grep filtering.
+
+Options:
+  --grep <pattern>   Filter log output (supports regex, e.g. "fixture|match")
+  --since <duration> Show logs since duration (e.g. 10m, 1h, 30s)
+  -n <lines>         Show last N lines (default: all)
+  --no-follow        Dump logs and exit (don't follow)
+
+Examples:
+  showcase logs mastra                          # follow all logs
+  showcase logs aimock --grep "fixture|match"   # filter for fixture matching
+  showcase logs mastra --since 5m --no-follow   # last 5 minutes, exit
+  showcase logs aimock -n 100 --grep "404"      # last 100 lines with 404s
