/* LCN-NAV3 2026-10-05 START — 导航精细化(取代 LCN-NAV2):更窄更静的深色顶栏 + 与顶栏栅格对齐的白色大面板;发丝线(1px)分隔、8px 节奏、
   细字重/宽字距、慢而柔的缓动 cubic-bezier(.22,.61,.36,1)(300–550ms)、减少花哨的逐项错峰、服务/登录面板补足大图版式。
   只学习高端汽车品牌官网的设计原则,未使用任何第三方代码/字体/Logo/图片。
   关闭整套效果:还原备份 index.html.bak-nav3-20261005(回到上一版);或删除本 <style id="lcn-nav3"> 与 <script id="lcn-nav3-js"> 两块,并同时删除 "服务" 面板里的 .lcn3-feat 一行。 */
