/* —— 现场共创坞：可收起 ——————————————————————————————————————
   2026-09-11 补。这个坞是 position:absolute 钉在画布底部中间的，
   644×164，加上 22px 下边距，吃掉画布可见高度的约四分之一，而且没有
   任何关闭入口。更要命的是：点「加入约束」生成的新节点就落在坞的正下方，
   被坞自己挡住——功能其实跑通了（节点数 12→13），但人看不见结果，
   反馈又只闪在屏幕右上角的 #feedback 里，于是感觉「点了没反应」。
   所以这里补两件事：一是能收起（收成胶囊，不是彻底消失——演示中途还要用），
   二是把共创相关的那条反馈就地回显在坞里，让动作在眼睛看的地方有交代。 */
