/* ============================================================================
 * uw-login-gate.css —— 「银河之门」登录页（TS 客户端专用）
 *
 * 设计：深空战场全屏底图 + 单块玻璃拟态容器（左品牌叙事 / 右登录卡）。
 * 命名：全部 uwx- 前缀，与 Blazor 镜像的 .uw-login-* 完全隔离，互不影响。
 * 依赖：仅 /img/login/login-void-gate-2026.webp 两张底图 + Font Awesome。
 * 归属：**Vite 端专属文件**（真源 Shared.UI/wwwroot 里没有），已登记在
 *       uw-client-ts/scripts/assets-manifest.json 的 tsOnly 清单，同步脚本不会覆盖/删除它。
 * 主题：本页固定为"深空暗场"，不随 day/night 切换 —— 登录是品牌门面，
 *       浅色卡片内的文字对比度已按浅底深字单独给定，两个主题下观感一致。
