/* ==========================================================================
   优居严选官网 · 样式 v5（沉浸式剧场版）
   --------------------------------------------------------------------------
   设计对标：Gaggenau / Bang & Olufsen / Apple 官网手法
   色板不变：深棕 #4A3B2C · 木金 #C4A87C · 米白 #F8F6F2
   设计原则：
     1) 全幅沉浸式 Hero（深色遮罩 + 大图 + 白色大标题）
     2) 标题用中粗字重（600）+ 大字号，有分量、够突出
     3) 深浅剧场节奏：深色开场 → 米白呼吸 → 深棕叙事 → 米白 → 深色收束
     4) 图片主导：套餐图、品类实景图直接作为视觉主角
     5) 金色发丝线、编号、kicker 作为精致细节层
