/* 产品详情页 v3.3 —— dd3.cc 版式 + 用户 6 项调整（2026-10-30）
 *
 * v3.2 → v3.3 变更：
 *   ① 规格表整段移除（.nr-specs / .nr-spec-table）
 *   ② 色卡从「5 列方块栅格」改为「横向一行排布」的胶囊 chip（名字不再截断）
 *   ③ FAQ 全部默认展开（JS 侧改动，样式不变）
 *   ④ 导航栏字体统一 + 放大一倍（独立文件 /_assets/noray/navfont.css）
 *   ⑤ 删除 Full product description 折叠区（JS 侧改动）
 *   ⑥ Contact Us 按钮链接修正为绝对路径 /contact/（JS 侧改动）
 *
 * 参照 https://dd3.cc/filament/pla-plus 的骨架：
 *   首屏两栏（左：图片轮播 / 右：eyebrow + 巨号标题 + Overview + CTA + 色卡）
 *   → 信任条 → Key Features | Applications（两栏）
 *   → OEM/ODM | Quality Control | Packaging Options（三栏，浅灰底）
 *   → FAQ（两栏）→ Related products → Request Sample 联系区
 *
 * 视觉语言照抄 dd3 的骨架但换成诺睿的品牌色：
 *   dd3  --exportas-blue #012169 / --exportas-red #c8102e
 *   诺睿 --nr-ink 深蓝墨色 / --nr-accent 品牌橙 #e58722
 *   边框 #dbe1e8、浅灰底 #f7f9fc 全部沿用 dd3 的数值。
 *
 * 命名一律 nr- 前缀：.row/.item 这类通用名会撞站点模板的全局样式。
 * 布局数字沿用 dd3：shell 1224px、栅格 gap clamp(1rem,3vw,2rem)、
 * 按钮 min-width 10.5rem / min-height 3.1rem。
