Go에서 채널을 사용하여 Goroutine 시간 초과를 안정적으로 재정의하려면 어떻게 해야 합니까?

package main

import (
    "fmt"
    "time"
)

func main() {
    c1 := make(chan int, 1) // Buffered channel with capacity 1

    go func() {
        for {
            time.Sleep(1500 * time.Millisecond) // Sleep for 1.5 seconds
            c1 <- 10 // Send value to channel
        }
    }()

    go func() {
        for {
            select {
            case i := <-c1:
                fmt.Println(i)
            case <-time.After(2000 * time.Millisecond):
                fmt.Println("TIMEOUT") // Not executed
            }
        }
    }()

    fmt.Scanln() // Wait for user input
}

timeout := time.After(2000 * time.Millisecond) // Create timeout channel only once
for {
    select {
    case i := <-c1:
        fmt.Println(i)
    case <-timeout:
        fmt.Println("TIMEOUT")
    }
}
