勉強配信チャンネル向けの、文字なしのフラットでミニマルなアイコンです。クリーム色の開いた本と、その上の小さな三日月が、やわらかな紺の円の中央にあり、どの大きさでもはっきり見える静かなシンボルです。チャンネルの雰囲気に合う自分のシンボルで作り直せます。

Create a finished 1:1 square profile picture for a study-with-me channel, designed to remain instantly recognizable when reduced to a 98 × 98 px circle. Center one simple, large emblem: a soft-cream open book viewed straight on, with two broad pages forming a clear symmetrical shape and a dark soft-navy spine; above it, a small cream crescent moon, its opening facing upward. Keep the moon and book visually distinct with generous negative space between them. Use flat matte vector-like shapes, clean precise edges, minimal geometry, and a restrained soft-navy and warm-cream palette with only subtle tonal variation. Place the emblem against a solid deep navy circular field; keep every important shape well inside the central circle with wide safe margins so corner cropping removes nothing. Strong light-dark contrast, balanced centered composition, no fine detail, no texture, no glow, no gradients, no extra symbols. No text, letters, numbers, or decorative border.
