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: product-mockup
Asset type: brand book photograph (realistic merch mockup) for the Reload brand manual
Input images: Image 1 is the exact legend artwork: "F5" drawn with large round white dots on a Reload-blue field, each character built on a dot grid. Use it as the legend to reproduce, not as a style reference; ignore its faint background grid.
Primary request: a macro photograph of one custom keycap in Reload blue (#0056FF) seated in the function row of a black mechanical keyboard. The keycap's top face carries the legend "F5" from Image 1 printed in white with the same dot construction: the F and the 5 made of round dots, both characters complete and centered. Every other keycap on the keyboard is matte black with no legend at all.
Scene/backdrop: the keyboard rests on a dark charcoal felt desk mat.
Subject: the blue F5 keycap in sharp focus; neighbouring blank black keycaps falling out of focus.
Style/medium: photorealistic macro product photography, 100mm macro lens, f/2.8, real PBT plastic texture.
Composition/framing: low three-quarter angle across the function row, the blue keycap slightly off center, shallow depth of field; landscape 3:2.
Lighting/mood: soft overhead studio light with a subtle rim along the keycap edges; quiet, premium.
Color palette: black, charcoal, graphite; the only saturated color is Reload blue #0056FF; the legend is white.
Materials/textures: fine-grain matte PBT keycaps, dye-sublimated legend, dark anodized aluminum case edge.
Constraints: the legend reads exactly "F5" in the dot style of Image 1, white, centered on the keycap top, no other characters; all other keys are blank; no brand names and no other logos.
Avoid: RGB backlighting, glow, neon, colored LEDs, any green, red, orange or yellow, legends on other keys, CGI look.

After the image is generated, copy the final PNG to ./batchA/keycap-f5.png (relative to the current working directory) and print the absolute path. Do not edit any other files.
