Santa Mug in Front of a Festively Lit Christmas Tree

Close-up, hyper-realistic image of a glossy emerald-green ceramic mug with a cheerful Santa Claus design on its side, held in a human hand in the foreground. Steam swirls from hot cocoa inside. In the softly blurred background, a Christmas tree is lavishly decorated with twinkling fairy lights, red and gold baubles, candy canes, ribbons, and silver tinsel. The scene is warm and cozy, lit by golden ambient light, with rich green, red, and gold tones. Focus on the mug's glossy glaze and the Santa print, with shallow depth of field and bokeh lights in the tree. High resolution, cinematic lighting.
