   问题：第 1 张是白底抠图（亮度 0.965 / 饱和度 0.006），
   另三张是实景照片（亮度 0.586–0.731），亮度断层导致不和谐；
   且 test-seating / workshop-a 在首页被重复使用两次。
   做法：四张全部换成 1600×900、亮度 0.50–0.62 同档、
   首页未占用的实景照片，统一 4:3 裁切与轻调整色调；
   标题改为均衡折行，消除 "quality-" / "first" 孤字。

   Why partners choose us — 三卡配图修正 + 曝光校准（2026-09-24）
   问题（用户反馈）：原三张图与文字主张不对应，且椅子"只看到半边"——
   根因有二：① 图片框为 16:9 + object-fit:cover，方形产品图被上下切掉；
            ② 原图构图本身不合格（产品抠图 / 椅子被桌子挡住）。
   做法：三张全部换成**实景照片**，主体完整、各自对应主张：
     1 OEM/ODM        → reviews/catalogue.jpg（**本站自有素材**：厂内扪皮工序实拍
                        「22-08 Upholster.jpg」。2026-09-30 由展厅图改为此图 —— 原因：
                        本公司展厅实际只有 3 个视觉场景（木格栅墙 / 绿色胶囊墙 / 白色展台区），
                        而首页有 4 处“房间照”位；原用的展厅图与「Model Wall」卡的绿色墙
                        **同属一个角落**，会被读成重复用图。改为非展厅的工艺实拍可彻底区分，
                        且对应 "bespoke development / our own R&D team"。）
     2 Low MOQ        → reviews/low-moq.jpg（Pexels：打包台人工封装单件纸箱 = 小批量语境）
     3 5-Year Warranty→ reviews/testing.jpg（**本站自有素材**：厂内扶手强度试验机，椅子完整）
   用图纪律：①③ 为**本公司自有素材**；② 为 Pexels 免授权可商用原图（Pexels License，
   免费商用、免署名），画面不含任何第三方产品。
   （曾用 Pexels 的椅子展厅网图作 ①，因画面是**别家椅子、非本公司产品**，已按用户要求撤下。）
   三张已逐张 1:1 复查：无第三方商标/logo、无文字水印；按卡片实际渲染亮度统一到同一档
   （校准后 ≈133.8 / 134.8 / 135.3，极差 1.5，高光溢出 ≤3.4%）。
   注意：① 的 URL 带 `?v=3` 版本号 —— 同名文件换内容后必须递增，否则老访客会命中旧缓存。

   About「Who we are」展厅轮播（2026-09-29）
   把原来的单张 showroom-2.jpg 换成 4 张自有展厅实拍自动轮播（淡入淡出）。
   素材取自素材包「办公+展厅图片\展厅 (2)~(5).jpg」，此前未在任何页面出现过；
   四张统一到同一亮度档（125）：渲染亮度 124.2 / 124.3 / 124.5 / 123.6，极差 0.9，
   高光溢出 ≤3.8%。纯 CSS 实现（无 JS），并遵守 prefers-reduced-motion。
