"Watch next" 是一张科普频道的 YouTube 片尾画面，采用简洁的极简风格。深蓝画面顶部是白色字母，下面是两个放视频的空框、一个放订阅按钮的圆圈，以及一行小字频道名。可以换成你自己的标题和频道名再做一张。

Create a finished 16:9 YouTube end screen for the science channel Daily Dose Science. Use a deep midnight-blue background with crisp white lettering and a clean broadcast-graphics layout. Set the exact headline “Watch next” prominently, centered across the upper portion. Below it, place two equal, completely empty landscape video-placeholder frames side by side, each with a thin white outline and a subtle cool-blue inner edge; leave their interiors clear for YouTube video overlays. To their right, place one large, empty circular subscribe-button placeholder outlined in white, with the exact label “SUBSCRIBE” centered beneath the circle. Add the exact channel name “Daily Dose Science” as a small, discreet footer at the lower left. Lettering is geometric sans serif: medium-weight, open counters, even stroke widths, clean terminals, generous tracking on the small label, no shadows or effects. Keep all text and frames sharply legible, aligned to a precise grid, with generous margins and no overlap. Add only a few fine cyan orbital arcs and tiny molecular-node accents near the outer corners, leaving the video boxes and circle unobstructed. Flat deep-blue field, restrained vector-like linework, subtle radial blue illumination behind the layout, high contrast, polished digital graphics, no extra text, no icons inside placeholders, no mockup or device frame.
