/* ============================================================================
 *  盛航云 · 登录页（独立页面）
 *  ----------------------------------------------------------------------------
 *  设计思路：
 *    左侧 52% —— 品牌视觉区：渐变底 + 网格 + 浮动的玻璃数据卡 + 三行卖点
 *    右侧 48% —— 大尺寸登录卡（440px），登录 / 注册 / 忘记密码三个面板切换
 *
 *  为什么不用弹窗：
 *    弹窗受容器宽度限制，输入框小、视觉局促；独立页可以做成整屏，
 *    空间足够，输入框 48px、按钮 50px，手感完全不同。
 *
 *  依赖：style.css 的 CSS 变量（--brand / --ink / --line / --radius 等）
