/* web/static/css/spine.css - 交接清单脊柱视觉层 (五站 + 折叠 rail + 站体控件)
 *
 * INPUT:  spine.templ / stations.templ 的 class 与 id (#spine .station* .facts* .fixes .fix* .checks* .rail-count).
 * OUTPUT: 脊柱 296px / rail 76px、站编号圆与连线、Interpret 事实表、Diagnose 九项清单、Propose 修复卡.
 * POS:    web/static/css - 纯样式; 由 cellsmith.css 的 token (:root) 供色, layout.templ 在其后加载.
 * PROTOCOL:
 *   - 调色板与密度来自 direction-2/style.css (docs/design/handoff-checklist-plan.md §2/§8 batch 2).
 *   - 从 cellsmith.css 拆出 (plan §10: 800 行上限), 拆分本身零视觉变化.
 *   - 变更时更新本头; class 增删同步 spine.templ / stations.templ.
