/* ORGANIZE —— 左右交替的滚动点亮时间轴。配套 ./live/ProcessTimeline.tsx。
 *
 * 三条规则，改之前先读：
 * 1. 左右交替用 .vg-tl-step.alt 显式挂在 02、04 行上，不能用 :nth-child()
 *    —— .vg-tl-rail 占了容器的第一个子元素位置，会让左右整体错一位。
 * 2. .vg-tl-icon / .vg-tl-node / .vg-tl-copy 都写死 grid-row:1。不写的话，
 *    .alt 行"先第 3 列、再第 1 列"的顺序会让网格自动排版给每个元素另起一行，
 *    看起来就是图标偏上、文字偏下。
 * 3. 行卡片是 .vg-tl-step::before（z-index:-1），不是 step 自己的 background
 *    —— 这样竖线才能压在卡片上、同时又被节点压住。
 *
 * 点亮的表现：未点亮 = 空心圆角方框；点亮 = 一圈 --live 细环套一个 --live 实心点，
 * 像状态指示灯。--live 是站上"在跑 / 已生效"本来就在用的信号色，这里不新增色相。
 *
 * 深浅色：色值全部走下面两组 --tl-* 变量，其余取 .stage 的 --fg/--fg2/--line2/--live。
