Как мне нарисовать серые полоски на границах секторов круга?

/* For example only --> */ body { margin: 0; display: grid; place-items: center; min-height: 100vh; background-image: url("https://i.stack.imgur.com/m9NKc.png"), radial-gradient(#fff8, #000f); background-position: 0 0; background-repeat: no-repeat; background-size: auto; }
