Design a tattoo-style minimal t-shirt design on a white background, featuring a compact triangular composition. At the base of the triangle, draw a tiny campsite: a pitched tent, a crackling campfire, and a log for sitting. Rising above that, inside the triangle, illustrate jagged mountain peaks in thin contour lines, with small pine trees scattered along the slope. Above the mountains, add a half-circle sun or moon, barely peeking out. All elements should be crafted with delicate black lines, and the entire layout should feel balanced, peaceful, and nature-focused, without any text or extra symbols.
