Create a square kawaii VTuber name logo composition, centered on a pale cream background with a very faint grid-paper pattern and light paper grain. Place one large rounded retro-computer window in the center, with a slim title bar, three tiny pastel dot buttons at upper left, a soft lace-scalloped edge on the lower panel, and a narrow blank info bar beneath the logo. Inside the window, render the exact text “Lumi” as the dominant line and “VTUBER” directly below it, smaller and clearly readable. Letterforms: custom bold bubble lettering, wide rounded proportions, soft round terminals, large open counters, gently bouncing baseline, every character distinct and legible. Give “Lumi” a smooth top-to-bottom baby-pink-to-lavender gradient, a clean white inner outline, and a slightly darker lavender outer sticker outline joining the word into one cohesive logo; add one small heart accent beside the name without covering any letter. Set “VTUBER” in compact rounded uppercase lettering in lavender with a fine pink outline. Flat vector-like finish with restrained soft white highlights, no 3D extrusion. Use soft even daylight, gentle highlight bloom and soft contact shadows. Scatter a few small sticker accents only around the outer edges of the window: four-point sparkles, tiny stars, a puffy cloud and a ribbon bow; keep generous breathing space around the lettering. No other words, no characters, no watermark.
