Create a finished 16:9 landscape desktop wallpaper for a laptop. Classic Halloween night as a clean, flat illustrated scene with fine paper grain and a little soft mist drifting between gravestones. Arrange the composition in two clear territories: keep the left 44% calm and open, with uncluttered indigo-purple night sky for the title; place the haunted scene across the right half and along the lower edge. On the right, a huge full moon sits high in the sky behind a crooked haunted house with sharply peaked roofs and a few glowing windows. Moonlight rims the house, twisted bare trees, crooked graveyard fence, and scattered gravestones in crisp silhouette. A row of glowing jack-o'-lanterns anchors the ground; a few small bats cross the moon. Cool moonlight is the base light. The pumpkin lanterns and house windows are the only warm light sources. Use deep indigo-purple night, pumpkin orange, moon white, and a restrained slime-green accent in one tiny detail. Keep the left title area clear of scenery and high-contrast enough to read at wallpaper scale. On the left, render the exact words "Happy Halloween" as the only text, large and clearly readable, arranged on two lines and aligned to the left. Use bold, heavy, upright display sans lettering with wide flat strokes and open counters. At flat stroke ends—including crossbars and the tops and feet of capitals—flare small bat-wing tips with two or three pointed lobes and shallow curved cuts; keep the wings subtle, no wider than half a stroke, and never obscure the letter shapes. Set the letters in luminous moon white, with cool light from above and a faint pumpkin-orange glow rising from below. Preserve generous margins and keep all text fully within the left sky. No extra wording, borders, interface elements, or objects behind the title.
