"Hoshi Byte" 是一个 Y2K 像素风频道横幅：淡紫和薄荷色像素字放在像素桌面窗口里，配一台复古小电脑图标和鼠标指针，标语写每周日更新，四周是像素蝴蝶结、爱心和星星。

Create a finished 21:9 YouTube channel banner for “Hoshi Byte”. Keep all important text inside the central safe area for banner cropping. Use a bright Y2K pixel desktop interface: pale cream-white background with a faint lilac grid and fine paper grain; lilac and mint are the main colors, with small baby-pink accents. Soft even daylight, gentle highlight bloom, and soft shadows only. Composition: a large rounded computer-window panel spans the central area, with pixel-stepped corners, a slim lilac title bar, three small mint, pink, and lilac dot buttons, and a slim info bar along its bottom. Set the exact eyebrow copy “CHANNEL ONLINE” in the title bar. Inside the window, place the dominant headline “Hoshi Byte” in bold, wide, unmistakable 1980s arcade-marquee pixel lettering. Construct every glyph from uniform grid-aligned square blocks with visible one-pixel gaps; use angular pixel staircases for diagonals and curves, strong two-pixel strokes, and hard color boundaries without anti-aliasing. Lilac and mint block colors alternate across the headline with a subtle pixel-offset shadow. Directly below the headline, set the exact supporting line “NEW VIDEOS EVERY SUNDAY” in smaller, highly legible pixel lettering. Make the words sharp and correctly spelled; add no other text. On the right side of the window, place a small pixel-art desktop mascot: a rounded mint computer with a lilac screen showing a simple four-point star, plus a tiny cursor arrow. Scatter a few small pixel hearts, four-point sparkles, stars, and one ribbon bow near the outer edges, leaving generous open space around the text. Bright cream background, pastel UI colors, crisp pixel geometry, clean hierarchy, polished 2D graphic finish. No photorealism, no dark background, no neon saturation, no extra lettering, no logos or watermarks.
