Overview

IO delegator that flushes the underlying IO after every write. We wrap ‘$stdout` in this for the default logger so log lines appear immediately when stdout is connected to a pipe (foreman, systemd, k8s). Without it, the C-stdio default switches from line-buffered to fully-buffered for pipes and log output piles up in a 4–8KB buffer until the process exits.

The wrapper is local to the default logger — apps supplying their own ‘c.logger = …` retain full control over flushing.

#close ⇒ Object

Declared explicitly so the type checker sees us satisfying ‘Logger::_WriteCloser`; SimpleDelegator forwards `close` via `method_missing`, but Steep doesn’t follow that.
