「HERO NIGHT」は、ダークで高級感のあるアールデコ調の、縦型ハロウィンイベントポスターです。磨かれた金色の立体的な大文字が2行に積まれ、ネイビーの背景にはうっすらと扇形の模様があり、小さな「2026 · Halloween Edition」の行の上に細い矢印の区切り線が入っています。イベント名、年、エディションの行を自分の内容に差し替えて、揃いのポスターやストーリー用画像を作れます。

Heroic authority lettering — letters as identity marks of power: bold, monumental, commanding. Strong single key light defines high-contrast form. Letters feel physically constructed — cast, forged, embossed, or built — not printed. Background: deep dark field (navy, charcoal, or black) maximizes letter contrast and gravitas. Hard cast shadows anchor letters as solid objects. Composition: letters fill frame as absolute subject. Deep midnight navy to near-black gradient background, rich and theatrical. Faint geometric Art Deco ornament pattern ghosted into the background at very low opacity — angular chevrons and fan shapes from the 1930s design vocabulary. Two narrow amber torch-light streaks from the upper corners cast warm amber pools downward, barely touching the letter tops. Primary text: "HERO NIGHT" as large compressed geometric Art Deco gold relief letters centered in the upper half at 68% of frame width — warm amber-gold face, raised inner ridge double-outline, recessed shadow groove, polished bright gold upper faces in warm directional light. Below, a thin decorative Art Deco rule line centered at 30% width. Secondary text: "2026 · Halloween Edition" in smaller compressed Art Deco lettering, centered below the rule line at 42% of frame width — same antiqued gold treatment, lighter weight. Warm amber directional key light from upper-left. Cool midnight sky fill in shadow zones. The register: the invitation card of a 1930s Golden Age hero society event. 9:16 vertical — print-ready poster format.
