;  sample_webview2.hsp
;
;  hspwebview2.dll 基本デモ:
;    - HSP ウィンドウに WebView2 を貼り付け
;    - Google を表示
;    - ボタンで JS を実行 (document.title を取得)
;    - JS 側から postMessage されたメッセージを受信して画面に表示
;
;  事前準備:
;    plugins\win32\hspwebview2\Release\hspwebview2.dll   (32bit)
;    plugins\win32\hspwebview2\Release\hspwebview2_64.dll (64bit)
;    を実行時ディレクトリに配置。
;    hspwebview2.as は package/win32/common/ に配置 (本リポジトリでは
;    iron_webview2.hsp 経由で #include "hspwebview2.as" している)。
