/* =============================================================================
 * 网络拓扑工坊 · Topology Studio —— Module C 互通分析 / 端口状态 样式
 * 沿用全局设计变量（--bg / --panel / --accent / --mono / --text / --muted /
 * --danger / --online / --border / --shadow / --radius），适配深/浅主题。
 *
 * 说明：本模块未向 NTS.Canvas 注入高亮 API（避免改动 canvas 渲染）；如需在画布
 * 高亮异常链路，可后续为 NTS.Canvas 增加 highlightLink(id, cls) 并把 .link-anomaly
 * 应用到对应 <line>/<path> 元素。此处仅提供 class 定义备用。
