在桌上型電腦前工作的極簡火柴人

Create a minimalist stick figure character in a simple, hand-drawn style using thin white lines on a plain black background. The stick figure is composed of straight lines for the body and limbs, with a circular head featuring two small dot eyes and a straight line for a mouth. Draw the character sitting at a desktop working on a computer, ensuring the pose clearly conveys the action in a clean and expressive manner. Keep the overall design simple and minimal, with no shading or intricate details.
