"stay quiet" 是一张黑白壁纸海报，风格昏暗、带颗粒感，近似黑色电影。一个穿连帽外套的孤独身影背对镜头，站在被雨淋湿的人行道上、亮着的路灯下，远处有车灯，底部有一行字距很宽的小字。你可以把 "stay quiet" 换成自己的名字、引语或日期来重新制作。

Create a finished 9:16 vertical black-and-white phone lock screen. A solitary, anonymous figure seen from behind stands beneath a single streetlight in steady rain, placed in the middle-to-lower portion of the image. Make the figure large enough to read clearly but leave generous dark negative space around it. A hard, single-source streetlight carves a bright edge along the figure and catches rain streaks and the reflective wet pavement; the surrounding street recedes into crushed blacks with only a few distant, softly blurred lights. Use pure black, white, and greys only. Render as grainy high-ISO black-and-white film photography with shallow depth of field, slight motion blur in the rain, visible fine film grain across the image, and a soft dark vignette at the corners. Keep the upper 25% especially clear and dark, with no objects or lettering there, reserved as open negative space for a phone clock. Set the exact words “stay quiet” in small, understated lowercase lettering at the bottom center, with generous letter spacing and a clean, light-weight sans-serif form in soft white; keep it legible but secondary to the scene. No other text, no logos, no added red, and no clock or interface elements.
