/* 导航宽度守卫 —— 主导航从 9 项加到 11 项（新增 FAQ / 中文）之后的溢出防护。
   实测依据（浏览器 canvas measureText，导航字体 600 .93rem）：
     原 9 项文字 475px + 8×gap22 = 176 + CTA 按钮 126 + 品牌块 171 + 行内 gap 16
     = 964px；容器内宽 1080px（viewport ≥1160px 时 .wrap 恒为 1120-40），余量 116px。
     新增 FAQ 28px + 中文 30px + 2×gap 44px = 102px → 合计 1066px，余量只剩 14px。
   所以两条纯增量规则：
     ≥1281px：gap 收到 18px，余量回到 54px（跨系统字体渲染差异也吃得下）；
     ≤1280px：直接折叠成汉堡菜单 —— 原本 960px 才折叠，而 961~1280px 这段
              容器内宽不足 1080px，加了两项之后本来就会溢出。
   两条都不改 960px 以下的既有行为（下面那组属性与 960px 块里的完全相同）。 */
