// 당겨 여는 풀 노브 — 노브를 아래로 당기면 잠깐 늘어났다가(scaleY, 줄기에 붙어 있으니 원점은 위)
// 잠금이 풀리며 덮개가 열리고(lid, rotateX + perspective), 손을 놓으면 제자리로 돌아간다(transition).
// 열림은 글자(잠김/열림)와 aria-expanded 로도 전달된다. 정적 드래그는 --pull 변수 하나로 당김+늘어남을
// 함께 구동하고, 격자 미리보기(.is-demo)만 루프 키프레임. 사람이 노브를 만지면 JS 가 .is-demo 를 뗀다.

// PullKnob — vanilla 판(run/013/demo/06-skeuo-pull-knob) 의 React 포트.
// 노브를 아래로 당기면 잠깐 늘어났다가 잠금이 풀리며 덮개가 열리고 손을 놓으면 제자리로 돌아간다.
// 당김값 --pull(단위 없는 수) 하나가 이동과 늘어남을 함께 구동한다. 값·타이밍은 vanilla 와 같다.
