/**
 * @file ICardSet.ts
 * @description 商品/药品卡池独立配置
 *
 * 职责：
 *   定义所有商品/药品卡的静态数据，与技能卡池（SCardSet）和装备卡池（EquipSet）分离。
 *   商品/药品为一次性消耗品，购买后立即触发一次 buff 效果（如治疗、护盾、属性强化等）。
 *
 * 设计：
 *   - 参考 SCardSet.ts 结构，但商品是"只触发一次的 buff 技能"，而非"多次触发的攻击技能"。
 *   - trigger_type 统一为 Instant（即时触发）。
 *   - t_times 固定为 1（只触发一次）。
 *   - kind 为 CKind.Potion（药水类）。
 *
 * 依赖：
 *   - CardSet —— CardConfig / CardType / CKind / CardTriggerType
 *   - SkillSet —— SkillOverrides
