Unmotivated Hamster Manga Panel

Prompt

Create a square black-and-white manga panel illustration of a very round, fluffy hamster lying on its back on a tatami mat floor in a traditional Japanese room, looking completely unmotivated and sleepy. The hamster is the central subject, huge and pear-shaped with tiny paws resting on its belly, two little feet sticking up at the bottom, small ears, half-closed eyes, and a small open mouth. Use delicate ink linework, cross-hatching, manga screentone texture, and soft fur strokes, with a cute deadpan comedic mood. Add one large irregular speech bubble above the hamster on the left containing Japanese text: {argument name="speech bubble text" default="やる気が\nログアウト\nしています"}. Include exactly 3 small thought-bubble dots leading from the hamster toward the speech bubble. On the right side, place a small standing spiral-bound desk calendar sign angled in perspective with Japanese text: {argument name="calendar text" default="本日の予定\n・何もしない"} and a tiny doodle of a hamster face near the bottom. Show the room details: tatami weave lines and dark fabric borders, a sliding door or wall panel in the upper right with a round black pull handle, a patterned floor cushion partially visible on the left edge, and a round cushion or small plush-like mat partially visible in the lower right. Keep the composition clean and mostly white, with the hamster occupying most of the lower center, humorous and cozy. No color, no photorealism, no extra characters, no watermark.
