   Magic House Prefab — 本站样式层（叠在 base.css 之上；base.css 由 _src/theme.py 生成，只当版式骨架）

   定位：集装箱房屋的生产厂家。不是民宿、不是精品酒店。
   所以整站是「白天的厂区」，不是「傍晚的木屋」：

   - 明暗：以亮为主。浅钢灰打底、白色卡片；深色只留三处——首屏照片、室内实景、页脚。
           整页深色沉浸是酒店的手法，厂家不靠它撑质感。
   - 玻璃：毛玻璃保留，但主要形态翻成浅色磨砂（白玻璃 + 白高光描边 + 真实投影）。
           深色磨砂只用在压着照片的控件上（顶栏、询价条、角标、照片里的说明条）。
   - 颜色：蓝图蓝。工程图纸本来就是蓝的，和图纸网格、尺寸标尺是同一套逻辑。
   - 字：标题 Inter 600 + 紧字距，像钢印；规格 / 编号 / 读数一律等宽。
   - 结构：工程图纸的语言贯穿全站——1px 发丝线、带刻度的标尺、图号编号、
           零件明细表式的参数行、方角铭牌。圆角收小，产品是制造出来的东西。

   类名沿用原有的 .tone-*，但含义已重新定义（见「区块色调」一节）。

   版式
   原来的骨架是从机械站沿用的：每个区块都是「眉标 + 同样大的标题 + 下方等分网格」，
   padding 一律 110px，整页滚下来像同一个模板刷了七遍。这一节重排页面级的构成：

   1. 标题分级   主张区块（制造 / 产品系列）用大标题，支撑区块（现货 / 案例 /
                 流程 / 问答）小一号。首屏 > 主张 > 支撑，滚动时有大小交替。
   2. 节奏分级   留白按内容轻重分三档，而不是均匀铺开。
   3. 双栏陈述   首屏下方那段话原来独占一屏、四个数字又占半屏；改成左边陈述、
                 右边一根数据柱，密度提上来。
   4. 工序轴     交付流程原来只是四张图并排；改成图纸上的工序线 + 节点编号。
   5. 破等分     案例三张卡原来三等分，与上一个区块的产品网格撞版；首张跨两列。
