Transparent Window Alpha Demo

Create a clean demonstration image on a black canvas showing a white-framed four-pane window graphic with transparency effects. The main subject is a realistic front-facing window centered slightly left, with a thick glossy white frame, beveled edges, a horizontal and vertical crossbar dividing the glass into exactly 4 rectangular panes, and a small sill at the bottom. Behind and through the window is a gray checkerboard transparency pattern, and the glass panes should show the checkerboard faintly with about 50% alpha, plus subtle bluish tint, soft reflections, and two diagonal light streaks. Around the window, include a larger semi-transparent checkerboard rectangle with alternating dark gray squares on the black background to clearly indicate transparency. At the top right, add one rounded blue speech-bubble label containing the Japanese text {argument name="instruction text" default="窓枠と窓の画像、背景透過、窓の部分は50%のアルファ値とする"} in white sans-serif type. At the bottom left of the checkerboard area, add one small dark rounded button labeled 「編集」, and at the bottom right add one small circular dark button with a white upload/share arrow icon. Keep the composition minimal, with no extra objects, no watermark, and crisp UI-like presentation.
