/* Block 2 + Block 3 合并（v5）：visibility:hidden + height:0 折叠（不再用 position:absolute）。

   绘图节点：.node-image-box 之后所有 sibling（.node-input-section / 无 class 内联 padding
   包装 div / .agent-lib-panel）
   视频节点：.video-workflow-empty + .video-workflow-card

   ⚠️ 为什么选 visibility:hidden + height:0 而不是 display:none 也不是 position:absolute：

   一、display:none（v3 用的）：浏览器把元素从 render tree 拿掉，包含的富文本 textarea
       （.node-textarea / .video-workflow-prompt 都带 @图片1 token chip 的 inline 富
       内容）的 layout/paint 状态被丢弃。tiny-LOD 退出后 display:block 重新进入，
       浏览器跳过对这种富文本框的重渲染——结果就是用户看到的"文字被黑遮罩盖住，
       点一下节点才显示"。

   二、position:absolute + left:-99999px（v4 用的）：理论上能保留 render 状态，但
       它把 .node-input-section / .video-workflow-card 变成了 textarea 的新 containing
       block——tiny-LOD 退出时 absolute → static 切换，textarea 的 containing block
       又变回 .node。富文本 textarea 在 containing block 切换时浏览器仍可能跳过 inline
       chip 的 repaint。实测仍然遮罩。

   三、visibility:hidden + height:0（v5 当前）：元素**始终在 normal flow** 里、**始终
       是 display:block 状态**、**positioning 没动**。只是 visible=hidden 跳过 paint，
       height=0 + padding/margin/border=0 + overflow:hidden 让它占 0 像素。tiny-LOD
       退出时只 visible 从 hidden→inherit，height 从 0→auto，**没有 display 或 position
       的切换**，textarea 的 containing block 和 render tree 位置都没动过，inline chip
       的 layout 也连续维持，浏览器没理由跳过重绘。

   display: block !important 用来压住既有的 `.node-input-section { display: none }` 全局
   规则（line ~16150），让 visibility:hidden 真正生效。 */

/* Block 4：覆盖 image-gen / video 节点的 inline height —— 让 .node 外壳跟着内容塌缩。
   根因：[core/node-base.js:560-564] resetNodeSize 在创建节点时给 .node 设了 inline
   style="height: 520px"（image-gen）/ "height: 380px"（video）。Block 2/3 把内部内容
   全 display:none 之后，外壳因为 inline height 还在原高度撑着，下半部分就显示为一块
   空白的深色矩形（.node 本身的 background）。
   用 !important 把 height/min-height 改成 auto/0，让 .node 自动收缩到 visible 内容
   （顶部 label + 预览框）的高度。height: auto 优先级低于 inline style，但加 !important
   后 CSS 可以战胜 inline style。
   组框 bounds 在 LOD 切换由 static_group_system.js 的 LOD guard 冻结，节点 height
   变化不会触发 ResizeObserver 让组框塌；连接线 anchor 跟着 .node 几何走，tiny-LOD 下

/* === Media upload status badge ===
   Tiny corner badge on an image/video node that signals cloud upload state.
   Originally a full overlay (half-transparent mask) but users felt it
   "locked" the node while uploading — even tiny 58KB images felt slow.
   Now it's a 24px badge in the top-right corner of the visual frame:
     uploading  → orange spinner (small circular badge)
     retrying   → yellow spinner (same shape)
     failed     → red pill with ! icon + "重传" button (slightly wider)
   The node itself stays fully interactive throughout — drag, edit, connect
   all work while upload happens silently in the background. Badge fades
   out on success (cleared by setNodeUploadState in nodes/media-upload.js). */
