⁠What is Attune?

Attune is a Kubernetes operator that automatically right-sizes pod resource requests and limits using In-Place Pod Resize (GA in Kubernetes 1.35; beta enabled by default in 1.33–1.34; alpha since 1.27, still feature-gated on 1.32; Attune requires 1.32+ for /resize). No pod restarts by default, no HPA conflicts, graduated safety controls.
