   18. 前台按钮统一风格（对齐文章页评论提交按钮 #commentform #submit）
   --------------------------------------------------------------------------
   设计令牌取自 iris/style.css 的 #commentform #submit：
     渐变 135deg #2f8fd0 → #135e93 · 圆角 10px · 投影 0 8px 18px rgba(19,94,147,.22)
     hover 上浮 1px · 焦点环 #43b8ff
   只覆盖 UserCenter 插件模板的按钮，插件文件零改动（升级不丢样式）；
   尺寸（padding / 字号 / 宽度）一律沿用各按钮原值，缩放行为不变。
   分级：Primary = 每屏唯一的主动作；Secondary = 并列的次要动作（白底描边）。
