/* ==========================================================================
   登录 / 注册 / 找回密码 —— 独立页外壳（深紫玻璃 + 金色点缀）
   --------------------------------------------------------------------------
   作用域全部在 .rg- 前缀下，不与 bootstrap / default_pc / .au-* 冲突。
   这三个页面原来直接套 bootstrap 的 form-control + nav-tabs，
   跟站内深色导航和登录浮窗（.au-*）完全不是一个体系，所以单独抽一套。
   表单 name / id / 提交接口保持原样，只换外壳。
