No workbook-only SKU. No combo SKU. Checkout product ids: book | stack only.

Companion app (only public app URL): https://invocationinc-ew2h-app.vercel.app

Buy buttons always render. If Stripe env is missing, /api/checkout returns 503 with checkout_not_configured.

STACK CTAs are primary red (#d10f28). Book CTAs are ghost. Sticky bar: $97 → $47 + timer + red Take the Stack.

Stripe setup

1. In Stripe Dashboard → Products, create one-time prices at 999 and 4700 cents.
2. Set Vercel / .env.local: STRIPE_SECRET_KEY, STRIPE_PRICE_BOOK, STRIPE_PRICE_STACK, NEXT_PUBLIC_SITE_URL.
3. Do not invent or commit Stripe Price IDs in source.

24h STACK timer

• localStorage key: ew2h_stack_deadline
• Set once on first visit (now + 24h). Refresh does not reset.
• Shown in: top bar, hero, story CTA, offer box, final CTA, sticky bar.

Newsletter MVP

POST /api/subscribe validates email, logs to stdout, and if NEWSLETTER_WEBHOOK_URL is set POSTs { email, source, ts } there. Otherwise returns 200 with no durable store.
