// Background throttling is left at Chromium's default (on). With it off, a hidden
// or occluded window kept animating at full frame rate: the GPU process sat at
// 50-80% of a core and the never-shown tray window at ~5% around the clock.
// Nothing durable lives in the renderer - logs, job history and routing are all
// in the main process and the Go services - and renderer pushes are buffered
// (see workloads.store), so a throttled window only delays paints, not data.
