深红压到近黑，一盏灯的事

Minimalist abstract gradient photography in a 16:9 widescreen frame: deep crimson bleeds into near-black through an ultra-smooth transition, framed by a slight vignette. Position the brightest crimson low and off-center, leaving wide, clean negative space for icon placement, with a subtle film grain running through it all.

极简抽象渐变摄影，16:9宽画幅：深红色以极为顺滑的过渡渗入近黑色，边缘带轻微暗角。把最亮的深红压在偏低、偏离中心的位置，留出大片干净的负空间供图标摆放，整体带一层细腻的胶片颗粒感。
