“I need cyber lettering for my CTF event Firewall Games”是使用 FontVibe AI 创作的未来科技文字效果。由发光蓝色线框三角网格构成的大写字母，半透明并有明亮扫描光束，悬浮在网格地面上方，四角有 HUD 括角。

Create a finished vertical 3:4 key-art poster for a cybersecurity capture-the-flag competition. All typography must be precise, fully legible, and rendered exactly as quoted. Deep midnight-navy gradient background (#030B22), with a faint electric-blue isometric grid emerging from the lower horizon, sparse HUD corner brackets, tiny coordinate ticks, and cold blue atmospheric mist. No logos, people, padlocks, keyboards, or decorative icons. Top-center, small technical eyebrow: "CAPTURE THE FLAG // 48-HOUR ONLINE CTF" in compact uppercase geometric sans lettering, translucent cyan, tracked wide, thin horizontal scanline cuts. The central headline dominates 68% canvas width across two lines: "FIREWALL" then "GAMES". Custom clean geometric sans letterforms with broad monoline construction, squared terminals, measured spacing, translucent projected-light faces. Build each character as a semi-transparent cyan-blue hologram: razor-thin Delaunay triangulation wireframe inside every letter, cyan fringe along left edges and deep cobalt fringe along right edges, regular horizontal CRT scan lines passing through the bodies, localized broken/flickering segments while preserving readability. The letters have shallow glass-like 3D extrusion, 15% of letter-width depth, beveled top faces, cold-white internal core fading to electric-blue outer edges. A narrow horizontal white-blue scan beam crosses the headline at mid-height. Add a controlled 5px electric-blue halo; keep the field clean and spacious. Below headline, centered: "BREACH. DEFEND. SOLVE." in white-blue uppercase, medium weight, tight precision spacing. Bottom-center event block: "SEPT 19–20, 2026" then "ONLINE // STARTS 18:00 UTC" in small cyan HUD text, separated by a thin luminous rule. Bottom edge: "firewallgames.ctf" in tiny, widely tracked pale-blue lettering. Crisp vector-meets-octane render, ray-traced glow, exact text hierarchy, no misspellings, no extra text.
