"BOLD SQUAD" 是一张多人游戏战队横幅，采用厚重的 3D 风格。红、蓝、黄、绿四色的亮面 3D 方块字分两行叠放，上方是小标题，下方是标语「Squad Up · Play Bold」。可以换成你自己的战队名、小标题和标语再做一张。

Create a finished Discord server banner, 16:9 wide format, for a multiplayer gaming clan. Dark charcoal-black studio background with a barely visible polished floor plane; no characters, weapons, game logos, controllers, or environmental scenery. The composition is a clean frontal 3D motion-graphics title card with generous safe margins for Discord cropping. Set the exact text “BOLD SQUAD” as the dominant two-line headline, centered and occupying 78% of the canvas width: “BOLD” on the first line, “SQUAD” on the second. Build every character as a massive custom chunky block display letter with 50–60% uniform 3D extrusion depth, square un-beveled corners, and tight controlled spacing. Each adjacent letter must be a distinctly different saturated hue family: cherry red, electric blue, sunshine yellow, lime green, hot orange, then repeat without same-hue neighbors. Front faces are ultra-glossy hard-candy lacquer with crisp upper-left specular highlights and saturated edge falloff; visible side extrusion planes are a much darker shade of each letter’s own hue. Cast long crisp shadows diagonally down-right at a consistent 45-degree angle, approximately one letter-height long. Add restrained mirror reflections on the black floor directly beneath the headline. Above the title, set the exact small uppercase text “MULTIPLAYER GAMING CLAN” in clean condensed white sans lettering, widely tracked, centered. Below the title, set the exact text “SQUAD UP • PLAY BOLD” in compact white uppercase sans lettering, centered, with a thin electric-blue horizontal rule on each side. Preserve clear hierarchy: headline first, clan descriptor second, motto last. Upper-left hard directional key light; faint cool-purple edge haze near the background only; subtle color halos immediately around the letters; deep black negative space. High contrast, sharp focus, ray-traced glossy reflections, professional 3D broadcast title-card render, no extra text, no misspellings.
