Visualize a minimalist yet captivating poster for a classic lemon black tea. The background is a soft gradient, transitioning from a sunlit yellow at the top to a deep tea brown at the bottom. Dominating the center of the poster is a pristine glass mug, filled with amber-colored black tea, and a slice of fresh lemon delicately floating on top. Droplets of condensation form on the outside of the mug, symbolizing its refreshing nature. Sun rays pierce from the top left corner, casting a gentle glow on the tea, making it look warm and inviting. At the base of the mug, there's a tag from a tea bag with the logo of the brand. Bold, elegant lettering above the mug reads, 'Classic Lemon Black Tea,' and a smaller, sophisticated font below the mug states, 'Refreshing. Timeless. Invigorating.' A subtle steam swirl rises from the tea, adding to its warmth and appeal,<lora:oldhkstyle:0.8>
