/* 登录页 · 3a 奶油底 · 厚边框 · 立体按钮
 *
 * 配色直接沿用 listening-home.css 的既有 token，不新造色板：
 *   底色 #FFF9F1 / 卡片描边 #F3E3C8 / 标题 #3D3428 / 主按钮 #FF9600 + #D97E00 下沿
 *   信息条走 .continue-banner 的 #EDF3FF+#D6E3FF；微信按钮走 .signed-badge 的 #E9F8EC+#BFEBC8
 *
 * 相对 listening-home 有两处刻意的对比度修复（该文件的原值不过 WCAG AA）：
 *   1. #FF9600 上的白字只有 2.2:1 → 主按钮文字改用深棕 #3D3428（5.6:1）
 *   2. 正文灰 #97876F / #A79375 → 加深为 #6B5B44 / #7A6A52
