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 mockup) for the Reload brand manual
Input images: Image 1 is the exact screen content: a halftone "R" symbol made of white dots on a Reload-blue field, with a faint regular grid of tiny dots across the rest of the field. Reproduce it 1:1 on the screen; it is not a style reference.
Primary request: a wide photograph of a dark tech-event hall moments before a talk starts. The whole back of the stage is a huge LED dot-matrix wall displaying Image 1 exactly: the blue field fills the wall, the white halftone R is centered, and the faint resting dot grid covers the rest of the field. Each white dot of the artwork is a round LED point, so the R reads as a matrix of lights.
Scene/backdrop: black stage floor, raw concrete side walls, black ceiling with a simple black truss; the room itself is only black, white and gray.
Subject: the LED wall with the R; in the foreground the seated audience seen from behind as dark silhouettes (heads and shoulders only, anonymous, softly out of focus); the stage is empty.
Style/medium: photorealistic editorial event photography, full-frame camera, 35mm lens, f/2.8, natural noise in the shadows, real venue texture.
Composition/framing: wide shot from the back rows at eye level, centered and symmetrical, the LED wall fills the upper two thirds of the frame, audience silhouettes along the bottom third. Landscape 3:2.
Lighting/mood: the LED wall is the only light source; its blue light rims the audience heads and falls softly on the stage floor; the wall is exposed correctly so every dot stays crisp and separate.
Color palette: black, charcoal, concrete gray, white; the only saturated color is Reload blue #0056FF.
Materials/textures: LED module seams barely visible as a fine grid, matte black stage, concrete walls.
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 (a normal R, never mirrored, never rotated in-plane), no merged or extra parts; dots densest inside the R with a thin halo of smaller dots along its edges. No text, letters, numbers or logos anywhere besides the artwork; no recognizable faces.
Avoid: bloom, glow halos, haze, light beams, lens flare, lasers, colored stage lights, any green, red, orange, yellow or purple light, CGI look.

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