/* ============================================================
 * Gerber 看图组件样式（后台 /admin/gerber 与前台 /gerber 共用）
 *
 * 为什么单独一个文件：原来这些样式躺在 admin.css 里，前台要用就得整包加载
 * 后台样式（会污染前台、也多一次 14KB 请求）。抽出来两边各自 <link> 一份，
 * 视觉与交互完全一致（2026-10-08）。
 *
 * 变量在 site.css 与 admin.css 里同名（--line/--muted/--bg-soft/--blue-600/--ink），
 * 这里都给默认值，缺了也不会变成透明黑。
