/* post-footer.css: 文章页脚补充样式。
   分享图标（#share .social-wrap）完全由 main.css 原版规则处理：
   - .article-footer .social-wrap：20px 网格、a.social padding:0 / border-radius:4px
   - .social-wrap .social：filter grayscale(100%) 默认灰度，:hover filter unset 变彩色
   - 全局 img{max-width:100%} 将彩色品牌图标约束到网格单元宽
   此处仅补充 main.css 未含的打赏（#reward）块样式。 */
