Here's why:\n\n**Decision:** Use context.WithCancel for graceful shutdown\n\n**Rationale:**\n1. All goroutines can check ctx.Done() to know when to stop\n2. It integrates well with Go's standard library\n3. Timeouts can be layered with context.WithTimeout\n\n**Implementation:**\n```go\nctx, cancel := context.WithCancel(context.Background())\ndefer cancel()\n\n// Pass ctx to all goroutines\ngo worker(ctx)\n\n// On SIGTERM/SIGINT\nsignal.Notify(sigChan, syscall.SIGTERM, syscall.SIGINT)\n<-sigChan\ncancel() // Triggers graceful shutdown\n```\n\nThis pattern ensures clean termination of all background work."}}
