+// ============================================================
+//  PdfBridge:报价插件(Form3)与 PDF 查看器之间的桥
+//  与 cadbt 的 CadBridge 保持相同的 API 形状:
+//  · 下行(Form3→查看器):SendPaCommand / ZoomToFrameHandle /
+//    DeleteFramesByHandles / MergeMasks / ClearHighlight
+//  · 上行(查看器→Form3):PaPicked / EntityErased / PaExited /
+//    F1/F2/F3Requested
+//  扒图逻辑:用户在 PDF 上框选 → 裁剪 → OCR 工作进程识别 →
+//  按 CAD 版语义组装 results(正向逐条/反向合并) → PaPicked
+//  → Form3 入表格;查看器在框选位置画彩色蒙版框。
