// test/ui/ammo-count.test.js — 设置「弹药数量」 (PR #552 by @IceCodeNew, ported in 0.2.6, DESIGN §31.9): the remaining ammo
// count under an ammo skill's bar is not part of the official HUD, so it is an option, off by default (the maintainer's
// decision of 2026-10-13, like 「官方伤害数字」). Settings normalisation, the dialog's toggle and its hint in every language
// pack, the field view's live setting, the diagnostics line. What the renderer draws: test/render/hud-readouts.test.js.
// Run: node --test test/ui/ammo-count.test.js
