Robot de Cérémonie du Thé au Lavis

A serene Japanese tea room rendered as a monochrome ink-and-wash illustration on aged parchment, with soft sepia-gray tones, delicate brush textures, and precise hand-drawn linework. On the right, a humanoid [service robot] kneels in seiza on tatami mats, featuring a smooth white shell, exposed mechanical joints in technical detail, and wearing a simple cloth apron tied at the waist. The robot gently bows its head as it pours hot tea from a cast-iron teapot into a small ceramic cup, with a faint curl of steam rising. In the center foreground, a low black wooden tea table holds exactly 5 tea objects: 1 dark ceramic vase with a thin branch of sparse leaves, 1 bamboo whisk standing upright, 1 tea bowl, 1 small teacup on a round tray, and the cast-iron teapot held by the robot. Behind the table, a hanging scroll displays a single enso circle painted in expressive sumi brushwork. On the left, tall shoji screens diffuse soft natural daylight across plain plaster walls with subtle age and ink stains. Wide cinematic composition, eye-level perspective, generous negative space, contemplative wabi-sabi sci-fi atmosphere.
