   TiekaCamp · NEON STREAM 版（v2：按参考稿骨架重做）
   骨架：
   ① 双层画框 —— 粉色底框 + 蓝色主框，各自微倾，里面是"屏幕"（网格地面 + 速度光线）
   ② 直播 HUD —— 主播牌 / LIVE / 信号电量 / 右侧互动栏 / 底部计数条
   ③ 斜切 —— 按钮、导航、进度条整体 skewX(-12deg)，文字反向 skew
   ④ 切角黑牌 —— 标题牌、标签用 clip-path 斜边
   ⑤ 星爆 / 贴纸字 / 气泡 —— 数据与强调用贴纸语言
   ⑥ 字体 —— ZCOOL 庆科黄油体（中文标题）+ Bungee（英文数字）
