{# trade-pro brand detail — 品牌详情精修（Task 11，次要页面收官）。
   设计参照（本轮无 cms 源对应）：上游 themes/automotive/versions/1.4.0/
   pages/brand.html 的信息架构——品牌横幅（面包屑 + 眉题/h1/导语 + 页内
   锚点按钮 + 品牌图）→ 车型/产品网格（section heading + "全部"动作位）→
   品牌故事（眉题 + h2 + 正文）；industrial 1.3.0 为同构薄形态。本模板以
   sf-tp 设计语言重组：sf-tp-page-hero（10c 内页 hero：封面底图 + brand-soft
   罩层）+ sf-tp-section-head/card-grid（10a 卡片系）+ sf-tp-article-body
   排版层双挂（10d）。
   数据事实（make_context 对 brand kind）：related = fields.brand 与页题
   （或 fields.brand 字段）一致的产品/车型集合——品牌页的产品网格只信它；
   派生品牌页（builder 从产品 brand 字段派生 /brands/<slug>/）body/cover
   恒空、summary 是平台占位串「相关品牌及产品」——导语按 authored 判定
   排除占位串（home.html 排除「首页」同款决策），空品牌不虚构介绍：
   无产品给数据无关的英文导语 + 空态卡，绝不编造品牌故事。
   面包屑 Brands 链接 /brands/（required_sections 恒保证该路由存在）；
   hero 锚点按钮锚到 #tp-brand-products（构建器豁免 # 锚点，10h 同款）。 #}
{% set tp_brand_summary = page.summary if page.summary and page.summary != '相关品牌及产品' else '' %}
{# 导语优先级：authored 摘要 > 数据派生计数（Jinja 三元与 or 的优先级易误读，
   显式分行赋值避免歧义）> 空品牌通用引导 #}
