- Epic: `EG_MODE=legacy|new` (legacy Playwright flow or neuer API-getriebener Claimer), `EG_PARENTALPIN`, `EG_EMAIL`, `EG_PASSWORD`, `EG_OTPKEY`

- Epic (new mode): Cookies werden unter `data/browser/epic-cookies.json` persistiert; OAuth Device Code Flow benötigt ggf. einmalige Freigabe im Browser.

- Login: `EMAIL`, `PASSWORD` global; per store `EG_EMAIL`, `EG_PASSWORD`, `EG_OTPKEY`, `PG_EMAIL`, `PG_PASSWORD`, `PG_OTPKEY`, `GOG_EMAIL`, `GOG_PASSWORD`

- Prime Gaming: `PG_REDEEM=1` (auto-redeem keys, experimental), `PG_CLAIMDLC=1`, `PG_TIMELEFT=<days>` to skip long-remaining offers
