+        Fix `ConsoleLogger` dropping DEBUG-level log messages. The `ConsoleHandler` used by the
+        default logger keeps java.util.logging's default `INFO` handler level, so `FINE` records
+        (SDK debug logs, including HTTP request/response logging) were silently discarded even
+        when `LogConfig` was configured with `LogLevel.DEBUG` and `silent(false)`. The handler
+        level is now set to `ALL` so the configured `LogLevel` controls filtering.
