// CyberMax games checkout: the per-game "full game" unlock + the Fun Pass (every game), copied into each game's web/ folder.
// Model (games lane GM, 9 Oct 2026; evidence docs/ceo/games-monetization-2026-10-09.md):
//   - Free demo: every game's daily challenge stays free for everyone, plus the first levels (OFFER.demo once the per-game
//     unlock is live; levels 1-20 until then). A level the player has opened is never locked again.
//   - Full game: ONE payment per game (OFFER.price, Stripe pack revenue/packs/stripe/<game>-full) unlocks every level,
//     mode, the daily archive and themes in that game, for good. Shown only when OFFER.live is true (owner-approved).
//   - Fun Pass = the all-games bundle: Monthly $2.99 · Yearly $19 · Lifetime $29.99 (pack revenue/packs/stripe/fun-pass).
//   - Portal builds (scripts/games/portals.py) never show a checkout; where the portal SDK offers rewarded ads, the player
//     may watch one to open the full game for an hour (shared/portal-adapter/cmx-portal.js CMXPortal.rewarded()).
// Buy: counted redirect https://data.cybermaxtools.com/buy/st-<pack>-<plan>?s=game-<id> -> Stripe checkout.
// After checkout the data Worker (/unlock/fun-pass or /unlock/<game>-full) checks the Checkout Session and returns with
// #cmx-pro=<code> (the full-game return adds ?unlock=full). The code on the receipt page unlocks any other device.
// No account, no cookies, nothing personal stored. (c) 2026 CyberMax. All rights reserved.
