"Nova Plays" 是一张方块建造类游戏频道的 YouTube 横幅，采用发光像素风格。泛着绿紫光芒的像素字母位于一行更新日之上，背景是有城堡、瀑布和灯笼的方块风夜景。可以换成你自己的频道名和更新日再做一张。

Create a finished YouTube channel banner in a 16:9 canvas, composed for a 2560 × 1440 image. Keep all lettering inside the central horizontal safe area so it remains visible on mobile and desktop crops. Render exactly these two text lines, with no other lettering: headline “Nova Plays”; supporting line “New videos every Friday”. Center the headline in the safe area, large and immediately readable, with the supporting line directly beneath it at a much smaller scale. Design the headline as custom voxel-pixel lettering: broad square forms, stepped pixel corners, open counters, consistent spacing, crisp block geometry. Give “Nova” a luminous acid-green face and “Plays” a saturated violet face, both with subtle bevelled edges, pixel-grid surface detail, and restrained colored emission. Keep the supporting line in clean, compact white pixel lettering with a faint green-violet edge glow. Build a night-time voxel landscape behind the type: layered cubic hills, block-built trees, a stepped stone path leading toward the center, and a few small cubic structures on the horizon. Use deep navy and charcoal forms with sparse green and purple luminous blocks echoing the lettering; add a dark indigo night sky with a few small square stars. The landscape frames the text without covering it; preserve high contrast and uncluttered negative space immediately behind both lines. Wide cinematic composition, subtle atmospheric depth, crisp pixel edges, restrained bloom, controlled rim lighting, ray-traced reflections on a few block surfaces, polished 3D render. No characters, no logos, no interface elements, no extra text.
