-              <p><strong>问题：</strong>钉住时面板从 ReactFlow 画布节点切到浏览器上层浮层，原本被画布 zoom 缩放过的视觉尺寸会丢失，表现为突然放大或缩小。</p>
-              <p><strong>改动：</strong>钉住瞬间只冻结当前屏幕缩放比例，不改面板自身 <code>framePanelScale</code>；右下角拖拽缩放也按冻结比例换算。</p>
-              <p><strong>影响：</strong><code>web/components/nodes/index.tsx</code>；钉住只改变“是否跟随画布”，不再顺手改变面板大小。</p>
+              <p><strong>问题：</strong>钉住后仍像自由浮层一样停在画布附近，用户继续缩放画布或调整面板尺寸时容易把它和画布节点混在一起。</p>
+              <p><strong>改动：</strong>钉住后统一吸附到浏览器左侧边缘，脱离 ReactFlow 画布缩放；钉住瞬间把当前可见大小转换成面板真实尺寸，之后只由右下角拖拽或标题栏按钮调整。</p>
+              <p><strong>影响：</strong><code>web/components/nodes/index.tsx</code>；钉住语义从“原地浮在上层”改为“左侧停靠工作面板”。</p>
