/* index.css — MiniCamp 欢迎页（站点首页 index.html）专用样式
 *
 * 页面定位：介绍 MiniCamp 是什么、有哪些内容、由谁举办，并提供「选择届次」入口
 * 与历届作品展示（作品数据来自 data/editions.json，见 data/README.md）。
 * 具体的赛程、规则、奖项与报名表单都在 2026info.html，本页不复述细节。
 *
 * 命名说明：本文件是站点首页的样式，所以随页面叫 index.css —— 与 2026info.css 并列。
 * 2026 赛事信息页（2026info.html）改名之前，这个文件名曾被那一页占用，注意别改错文件。
 *
 * 依赖：base.css（变量、按钮、站点头部、footer 等公共部分）。 */
