Fondo de pantalla minimalista y oscuro de Halloween, sin texto, con una sola calabaza iluminada. La pequeña calabaza naranja está en la parte inferior de un marco negro, con ojos triangulares y sonrisa dentada de luz ámbar, y proyecta un leve resplandor y sombra en el suelo. Añade tu nombre, saludo o fecha en el amplio espacio negro sobre la calabaza para crear tu propia pantalla de Halloween.

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.
