由 `Tools/economy_sample.py` 读取 `Config/Gameplay/greenfield.json` 生成。不计弹珠自然恢复。弹珠台按五个落区等概率取均值：糖果 {candy_mean:g}、金币 {coin_mean:g}。实际单次受路径影响。

## 对照设计稿

`GameDesign` 8.2 的首日上限是 **{DESIGN_DAY1_BALLS}** 枚弹珠：初始 20、签到 10、每日任务 15、免费补给 5、前五关首通 {design_stage_balls}。按同一口径合计得到 **{design_matched}**。现行 1-1～1-5 首通弹珠合计是 **{config_stage_balls}**，与稿一致。

稿中「10 发预计糖果 200、金币 520、券 1」。现行均值为糖果 {ten['candy']}、金币 {ten['coins']}、券 {ten['tickets']}，与稿一致。

## 首日获取上限

假设当天领完邮件、签到、三个每日任务、免费补给和教学目标，打通 1-1～1-5 并打开已掉落的绿野补给箱与碎片自选箱。自选箱只给碎片，不进下表钱包。溪口大礼箱要先通过 1-5，打开后另有金币 150、糖果 80、弹珠 5、券 1，未计入本表。

| 来源 | 到账 |
| --- | --- |
{chr(10).join(rows)}

合计：**{wallet(day1)}**。这是获取上限，不是要求当天花完。

## 七日回访

不打新关、不发射。每日未领奖励过期，下表按七天都当天领完。签到不循环。

| 来源 | 到账 |
| --- | --- |
{chr(10).join(week_rows)}

合计：**{wallet(week)}**。

## 卡在 1-5 之前

已通过 1-1～1-4，打不过溪口大角王。当天可领来源如下，不含为了拿糖果而发射的弹珠台产出。

| 来源 | 到账 |
| --- | --- |
{chr(10).join(stuck_rows)}

合计：**{wallet(stuck)}**。

- 训练到建议 Lv.5 需要糖果 {need_candy}。账上差 {candy_gap}，按均值再发射 {int(shots_for_candy)} 次可补上。主线不另扣体力。
- 进化需要金币 {need_coins}。账上差 {coin_gap}，按均值再发射 {int(shots_for_coins)} 次可补上。通过 1-1 后商店每天还能用金币换糖果，那是把金币换成糖果，不增加总资源。
- 进化需要碎片 {economy['evolveShards']}。1-3 自选箱提供 {shard_from_chest}，还差 {shard_gap}。重复伙伴每次 {economy['duplicateShards']} 片，不能把碎片换回捕捉券。

训练、进化和再抽一只伙伴都能从免费来源走到，碎片比糖果和金币更慢。
