霓虹深色地铁线路图

虚构城市「Orveka City」地下网络的简洁线路示意图，背景为近黑色（#0d0d14）。十二条彩色线路以45度角弧线交织，包括荧光绿、霓虹珊瑚红、天蓝、琥珀、紫罗兰等。站点为白色圆点，换乘站为多环标记。站名以紧凑无衬线字体显示，带轻微辉光效果。图例列出「Cerulean Line」「Amber Line」「Vantage Line」等线路名，整体呈现深色模式的未来感。

A clean transit diagram for the fictional underground network of "Orveka City", displayed on a near-black (#0d0d14) background. Twelve colour-coded lines arc and intersect across the canvas using strict 45-degree angles in the classic schematic style. Each line is a bold 4px stroke in a distinct vivid colour: electric lime, neon coral, sky cyan, amber, violet, and six others. Station dots are white circles; interchange stations are larger multi-ring markers. Station names are set in a tight grotesque sans-serif typeface in white, with a subtle glow effect where names overlap busy junctions. A legend sits bottom-left listing line names: "Cerulean Line", "Amber Line", "Vantage Line", etc. The overall aesthetic is crisp and futuristic, inspired by classic European metro schematics but with a contemporary dark-mode energy. No geographic accuracy implied — pure schematic topology.
