「NOVA」は、写実的な夜の墓地スタイルのハロウィン背景画像です。コウモリの飛ぶ満月、明かりのともる幽霊屋敷、墓石、鉄の門、光るジャックオーランタンが藍色の霧の中に並び、下部中央に「NOVA」と書かれた小さな金属プレートがあります。プレートの名前を自分のチャンネル名やチーム名、パーティー名に差し替え、空いた夜空にタイトルや詳細を入れられます。

Create a finished 16:9 spooky Halloween livestream background in a photoreal moonlit-graveyard style. Keep the central 50% of the canvas—roughly x=25–75%, y=18–82%—open, dark, and visually quiet for a webcam feed: a smooth deep indigo night sky fading to subtle low mist, with no moon, lettering, props, or bright details in this webcam zone. Frame it with graveyard scenery kept to the outer sides and bottom. At the upper right, place a huge full moon with a few small bat silhouettes crossing its face. On the left edge, a crooked haunted-house silhouette with a few pumpkin-orange glowing windows rises behind a bare twisted tree. On the right edge, add a crooked iron graveyard fence, sparse gravestones, and another twisted tree. Along the bottom corners, place a small row of jack-o'-lanterns with restrained candle-orange glow; leave the bottom center clear except for one small nameplate. Cool moonlight rim-lights the silhouettes; pumpkin lanterns and house windows are the only warm light sources. Deep indigo-purple night, soft drifting mist between gravestones, subtle fine grain, clear silhouettes, no busy detail in the webcam opening. Set the exact text "NOVA" on a small, centered, dark iron nameplate at the bottom, below the webcam area. Render the name in a bold, upright display sans with open counters and small bat-wing flares at flat stroke ends; keep every letter immediately readable. Moon-white lettering with a restrained pumpkin-orange edge glow. No other text, logos, borders, or overlays.
