// test/ui/loadout-rows.test.js — the 干员调配 roster as one list (0.2.2): the quick choices of PR #301 (by @farridge) laid
// out as one row per operator with aligned columns instead of three columns of cards (the owner's decision of 2026-10-08:
// 「三个竖排有点乱影响观感」), and the per-operator 潜能 / 练度 controls (「调配干员里自己设置吧，默认满潜满加成」): the row's skill
// / module buttons and selects (state, labels, what a tap sets), the detail's section, a 自选 slot's selects, the 局内数值 at
// the settings, and the css that keeps the columns aligned and the detail sliding over the list below 1000 px. Hook-free
// views drawn as vnode trees. (The browser side: test/ui/loadout.e2e.test.js.)
