// Player feedback after 0.1.0, report #6 (workstream WB): "凯瑟琳策略升级刷新的三个装备显示异常". The strategy 凯瑟琳
// (【定向投放】"每次升级调度中心时，在调度中心刷新随机3件装备，可以选择并获得其中1件") queues a free pick-one offer of three
// items; the shop bar drew every offer slot as an operator card (ChessCard on an item id: no art, the raw id as the name,
// tier I, no description) under the promotion reward's 晋升奖励 / PROMOTION header, and the reminder pill said
// 晋升奖励待选择. Now: m.private shop.rewardOffer says what made the offer (`source` 'merge' | 'special', `label` = the
// effect's name — effectsMeta.offerLabel), an item slot is drawn as an item card (FREE) and the header / pill name the
// offer (gameLogic.offerHeader; `queued` — "之后还有 N 项" / the pill's "+N" — when more offers wait behind it, e.g. a
// 定向投放 behind a promotion reward put off). The same path serves 娜仁图亚 见者有份 (two items), 寻呼模块 / 信标
// (operators, an item's name) and 松果's 特质. Real match paths for the server side; the bar's offer cards rendered as
// vnodes.
// The browser check (desktop + phones, real input) is test/ui/feedback1-offers.e2e.test.js (SP_E2E=1).
