Use the imagegen skill in its default built-in mode (the built-in image_gen tool). Generate exactly one image and nothing else.

Use case: photorealistic-natural
Asset type: brand book photograph (realistic signage mockup) for the Reload brand manual
Input images: Image 1 is the exact vinyl pattern (portrait 4:5): a field of dots that grow larger toward the bottom, with a large "R" left empty (no dots) as a negative silhouette. In the vinyl, every white dot of Image 1 becomes a frosted dot and every blue area becomes clear glass.
Primary request: a photograph of a frameless glass office door with frosted window vinyl applied over its full height following Image 1: frosted white dots, sparse and small near the top and dense near the bottom, with the R cut out as clear glass. Behind the glass, an open office with a few anonymous people, softly blurred, partly visible through the clear R and diffused behind the frosted dots.
Scene/backdrop: a bright office corridor with a polished concrete floor; the door has a black steel bar handle and minimal hinges.
Style/medium: photorealistic interior photography, 35mm lens, f/4, real glass reflections.
Composition/framing: frontal, slightly off-axis, the door fills most of the frame; portrait 4:5.
Lighting/mood: soft daylight in the office behind the glass, gentle reflections on the glass; calm workplace.
Color palette: white, light gray, black, concrete; neutral clothing on the people; if any saturated color appears it is only Reload blue #0056FF.
Materials/textures: thick clear tempered glass, frosted etched-look vinyl with crisp dot edges, black steel hardware.
Constraints: the R must match Image 1 exactly: two rounded blocks, the stem joined to the bowl (with an inverted-L shaped counter) and the separate diagonal leg whose rounded top-left corner sits inside the counter; same proportions and orientation as seen from the corridor (a normal R, never mirrored, never rotated in-plane), no merged or extra parts. No text, door signs, other logos or recognizable faces.
Avoid: plants, colored furniture, any green, red, orange or yellow, glow, gradients, CGI look.

After the image is generated, copy the final PNG to ./batchA/window-vinyl.png (relative to the current working directory) and print the absolute path. Do not edit any other files.
