/* ============================================================
   KCK.CASA — Certifications page (2026-09-02)

   方向：把"合规声明"做成可核验的证据墙。
     - 每张卡片 = 一条可核验事实：分类 / 名称 / 说明 / 持证方 / 签发机构 / 报告号 / 日期 / 范围
     - 图片型证书直接渲染缩略图 + 灯箱（复用 main.js 已初始化的 .img-popup）
     - PDF 型渲染文档块
     - 证据状态徽章：Document on file（绿）/ On request（琥珀虚线）/ Supplier-held（灰）
     - 底部 "Full disclosure" 主动说明我们不宣称什么（CertiPUR / FSC 等）
       —— 主动划清边界比含糊其辞更能建立 B2B 信任

   页面头图（.kck-page-hero）与底部 CTA（.kck-cta-band）在共享层 kck-design.css。
