テキストのないミニマルでダークなハロウィンのスマホ壁紙で、光るジャック・オ・ランタンが一つ描かれています。小さなオレンジ色のカボチャが黒い画面の下部にあり、三角の目とギザギザの口が琥珀色に輝き、地面にほのかな光と影を落としています。カボチャの上の広い黒い余白に、名前やあいさつ、日付を入れて、自分だけのハロウィン画面を作れます。

Create a minimalist Halloween phone wallpaper in a vertical 9:16 composition. Show exactly one small-to-medium jack-o’-lantern positioned low in the frame, centered horizontally and contained within the lower third. Its simple carved eyes and mouth emit a soft, warm amber candle glow from within the orange pumpkin rind; keep the face friendly and understated, not frightening. Use a plain, deep charcoal-black background with a faint, close shadow beneath the pumpkin. Leave the upper two-thirds almost entirely empty and uniformly dark for a clear clock and app-icon zone. Restrained detail, clean silhouette, gentle falloff of warm light only near the pumpkin, matte dark background, crisp high-resolution rendering. No lettering, no additional objects, no stars, bats, fog, borders, gradients behind the clock area, phone frame, clock, widgets, or app icons.
