    /* ===== 首屏标题避让左右切换箭头 =====
       症状：首屏 H1 的**首字被左箭头圆钮盖住**（390px 手机截图里 "专业法律服务 守护您的权益"
       的"专"整字看不见），偶尔连末字一起被盖。
       根因：.slide-content 是普通块（非 flex），标题左对齐；桌面端它有 max-width:900px 且居中，
       左右余量大所以没事；但 ≤992px 时 900px 列宽 ≈ 视口宽，标题就顶到了视口左边，
       而箭头是绝对定位固定在 left:34 / right:118（垂直居中，正好压在标题那一行）。
       实测 390 / 576 / 640 / 768 / 992 五个宽度**全部命中**（水平相交 34~54px）。
       修法：按箭头实际占位给标题留左右内边距（结构性避让），而不是缩小字号 ——
       这样后台把标题改长也只是换行，不会重新压到箭头上。
       数值：左 34+54+8=96、右 118+54+8=180（8px 为安全间隙），减去 .container 的 28px 内边距 → 68 / 152。 */

       手机上箭头缩到 40px 且贴边（left/right:10）、.container 内边距降到 16px，
       故标题只需左右各让 58-16=42px 即可（58 = 10+40+8）。
       字号同时降到 22px：让当前 13 字的标题在 274px 可用宽度内**单行放下**
       （实测 27px 时文本宽 332px，22px 约 271px），避免中文逐字折行把词组切断
       （CJK 允许字间换行，不控字号会出现 "…守护您 / 的权益" 这种难看的断法）。 */
