README/onboarding pass only, not a security review: the architecture is unusually clear, but one copy-paste trap will frustrate real-shop testers. Quick Start enables httpFallback while setting webhookSecret to process.env... || ''; the options table says the secret is required, and the controller rejects every webhook when it is blank. I would either disable fallback in the minimal path or show secret generation and fail fast.

I would also put the no-production-store-yet status near the top and add a staging-first regtest/testnet checkout recipe, tested Vendure/Node/wallet matrix, the 66-test command, and an exact issue-report bundle covering versions, relay, payment path, and redacted logs.

If useful, the $10 QuickScan returns five prioritized fixes, rewritten lead copy, and an annotated screenshot: https://shopstr.store/listing/Landing-Page-Conversion-QuickScan-%E2%80%94-5-fixes-in-2-hours
