A host that draws on the terminal (a TUI) cannot let the logger write to stdout or stderr, yet the records are worth showing inside the host. SetErrorHandler already covers internal diagnostics; SetConsoleWriter is its sibling for console output. - SetConsoleWriter(w) sends console output of every console_target to w, split's warn-and-above records included; nil restores stdout/stderr. It holds across ApplyConfig and is safe while logging. - One stored value: ApplyConfig and SetConsoleWriter publish the console writers through storeConsole; the processor's split branch now reads the stored warn writer instead of writing os.Stderr directly. - TestLoggerConsoleTargets becomes TestConsoleWriterTakesEveryTarget, which asserts where each target's records land; a second test checks that nil restores the configured writers. - README names both hooks for terminal hosts; the API doc's callback contract covers console writers. Verified: go build ./... ok; gofmt -l on changed files clean; go vet ./... ok; go test ./... ok (all four packages, under 1 s); go test -race on the new tests ok; mutation run 6 of 6 caught.
