+## Exception Handling

+- **Always use `logger.exception()` instead of `logger.error()` when catching exceptions**
+  - Don't include the exception in the message: `logger.exception("Failed")` not `logger.exception(f"Failed: {e}")`
+- **Catch specific exceptions** where possible:
+  - File ops: `except (OSError, PermissionError):`
+  - JSON: `except json.JSONDecodeError:`
+  - Network: `except (ConnectionError, TimeoutError):`
+- **Only catch `Exception` for**:
+  - Top-level handlers that must not crash
+  - Cleanup blocks (log at debug level)
