深紅壓到近黑，一盞燈的事

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.

極簡抽象漸變攝影，16:9寬畫幅：深紅色以極為順滑的過渡滲入近黑色，邊緣帶輕微暗角。把最亮的深紅壓在偏低、偏離中心的位置，留出大片乾淨的負空間供圖示擺放，整體帶一層細膩的膠片顆粒感。
