+# chrome-error-scan.sh - scan per-profile chrome logs for concerning patterns.
+# Self-contained: scans, compares against watermark, reports only NEW matches.
+#
+# Usage: chrome-error-scan.sh [--json]
+#   Default output: "profile:new_count" lines for profiles with new matches,
+#                   or "OK: no new errors" if clean.
+#   --json: output JSON {"profile": {"total": N, "new": M}, ...}
+#
+# Watermark: /home/super/Projects/NetVM/chrome-error-watermark.json
+# Patterns: FATAL, crash, segfault, out of memory (case-insensitive)
