/* ==========================================================================
   扬州市生物医药行业协会 — 业务组件 (components.css)
   --------------------------------------------------------------------------
   实现 DESIGN.md §5.2 全部 class：
     列表与筛选 / 卡片 / 文章 / 结构展示 / 侧栏 / 表单 / 搜索
   只引用 base.css 的 var(--c-*) var(--radius*) var(--shadow*) var(--gutter)
   var(--ease) var(--dur) 等令牌；不重复定义 base.css 已有的组件。

   新增色值说明（均由 base.css 令牌色改写为半透明，未引入新色）：
     - rgba(46,119,204,.18) ← --c-brand-500 半透明，用于输入框 focus 光晕
     - rgba(107,118,136,.12)← --c-ink-500 半透明，用于 .empty 的斜纹底
     - #f6c9d1 / #eddfb4 / #f0d9b5 / #7a5c0b / #8a6a0f / #f0d9b5
       ← 分别为 --c-red-600 / --c-gold-600 / --c-gold-050 的同族浅色边框与文字色，
         仅用于 .badge--red/.badge--gold 与 .notice-box--warn 的描边和文字对比度
   断点：1080px（列表密度）、860px（三/四栏→两栏）、620px（→单栏），与 base.css 一致。
