/* 下载区打赏按钮 · 前台样式
   按钮：实心玫红胶囊，挂在版本切换条右侧（nav 是 flex，margin-left:auto 顶到最右）
   弹窗：单张收款码 + 底部一句话 */

/* 打赏按钮
   位置：挂在 nav.lv-versions--inline 上，靠 margin-left:auto 顶到版本号那一行的
        最右端（nav 本身是 flex）。
   尺寸：照抄 log_versions 的 pub.css chip 规则（min-height 2.125rem / 圆角 9px /
        padding .35rem 1rem），跟版本号按钮同一形制。
   刻意不带 lv-versions__chip：pub.css 的 chip 选择器是 .lv-versions__list a，
        挂在 nav 上本来也匹配不到；不带这个 class 还能让 pub-variants.js
        彻底不把它当版本切换按钮处理。
   配色：后台四选一，见下面 --a / --b / --c / --d。 */
