popover

computePopoverLayout 纯函数选侧（prefer → 翻对侧 → 取大侧）；openPopover 负责 portal、跟随重算与外点/Esc 关闭。

示例

<div class="demo-row">
  <button class="btn" id="popover-demo-trigger">筛选 ▾</button>
</div>
<div class="popover" id="popover-demo-panel" hidden>
  <div class="form-field">
    <label class="form-label" for="popover-demo-input">包含关键词</label>
    <input class="form-input" id="popover-demo-input" placeholder="例如：overlay" />
  </div>
  <div class="demo-row" style="margin-top:10px">
    <button class="btn btn-sm btn-primary" id="popover-demo-apply">应用</button>
  </div>
</div>
