Create a vertical concept product poster. Large headline text: "Fast-Acting Happy Capsule". Show a small pill capsule with a rich coffee-green top and a transparent bottom, filled with many roasted coffee beans inside. Print a fictional round coffee emblem on the capsule; do not use any real brand name or real logo. Add small playful label text: "A cheerful coffee-bean concept for low-energy moments". Use a clean warm off-white background, polished product lighting, realistic capsule material, glossy transparent plastic, crisp coffee-bean texture, and minimal promotional layout. Keep all text legible and correctly spelled. Avoid medical dosage instructions, real health claims, real prices, purchase buttons, real brand logos, extra watermarks, warped capsule geometry, muddy beans, unreadable text, and low-resolution artifacts.
