"$20 a Day in Lisbon" 是一张旅行 vlog 的 YouTube 缩略图，采用明亮的街拍风格。带黑描边的厚实黄字叠在左边，背景是阳光下开满花、老建筑林立的坡道，右边一辆复古黄色电车正沿轨道爬坡。可以换成你自己的城市和预算。

Create a finished 16:9 YouTube travel-vlog thumbnail, 1824×1024 composition, designed to remain instantly readable at phone size. Show a sunlit Lisbon street with a recognizable classic yellow tram as the clear visual subject on the right. Use a vivid photographic travel-editorial treatment: warm direct sunlight, crisp blue sky, saturated yellow tram paint, pale façades, deep cool street shadows, sharp subject separation, high contrast, subtle natural film grain. Place the exact headline “$20 A DAY IN LISBON” in two stacked lines on the left, large enough to dominate roughly half the frame. Use ultra-heavy, wide, near-square display letterforms with near-zero stroke contrast and tight spacing; solid bright yellow letter faces, a thick clean black outline around every letter, and a restrained dark drop shadow for separation. Keep the headline fully inside generous safe margins. Compose the tram and street details to lead the eye toward the title, with no faces, lettering, or key details in the bottom-right video-duration area. Keep the background uncluttered behind the words. Render no other readable text, logos, channel names, play icons, timestamps, or interface graphics.
