/* submit-stations.css — Submit station full-screen form (.submit-* and field shake animation) */

/* ★ v3.8 提交电台 全屏滑入页 (submit-stations-view)
   ────────────────────────────────────────────────────────────
   - 复用 .category-detail-view 的 transform 滑入动画。
   - v3.8 改动:
     · 字段标签字号/对比度提升 (13px/0.85, 非 uppercase), 与下方 hint/placeholder 拉开层级
     · 直播流地址改为多行 input + ×, 提供 .submit-stream-list / -row / -input / -remove / -add 系列
     · 提交按钮从 header 右上角下沉到内容底部, 主按钮样式 (.submit-primary-btn) 大号实心蓝
     · 头部右上角恢复为 .category-detail-spacer, 维持 grid 三栏对称
