Impulse product engine + $2.99 Drop-Day Playbook (one-time, no-install)

[New1Direction]

Why

The consumer SEO traffic is mostly mobile + multilingual — it can't install a Chrome extension (QuickCatch) or commit to a subscription. So neither existing product is an impulse buy for it. This adds the opposite: a one-time, no-install, instant-on-page-unlock product priced for impulse.

What

• Reusable engine (worker/src/digital.ts): mode=payment checkout (no email pre-form — Stripe collects it, lowest friction) → success → verify payment_status==="paid" → render content + mint a 1-year re-access token (dlg:<token>) so buyers reopen it at /guide/read?t=… (no account). Add a row to PRODUCTS + a Stripe price to ship the next one (Calculator Pro is next on these rails).
• Product 1 — The Pokémon Drop-Day Playbook ($2.99): genuinely useful, real-method content (pre-drop checklist, store-by-store setup, retail-vs-resale margin math, grading-ROI framework, timing/scalper-traps) — no invented dates/prices. Mobile-first amber/dark sales page at /guide.
• Routes: GET /guide, POST /api/v1/guide/checkout, GET /guide/unlock, GET /guide/read.
• Exported STRIPE_API + createSessionResponse from stripe.ts for reuse.

Safety

• Fail-closed: 503 until STRIPE_PRICE_GUIDE is set — safe to deploy un-configured.
• 6 new tests (fail-closed, session-required unlock, token gating, sales render). Suite 261 green, typecheck clean.

To go live (owner, ~2 min)

1. Stripe → create a one-time price (~$2.99) → wrangler secret put STRIPE_PRICE_GUIDE.
2. Deploy.

Not yet (intentional, next steps)

• CTA placement on /drops + /guides + /tools (the traffic'd pages) — tell me where; it's a small follow-up.
• Guide content localization to the 12 SEO languages (gated content isn't SEO-indexed, so English v1 ships first; translate as buyers appear).
• Calculator Pro ($4.99) — next product on this same engine.
• Revenue still gated on confirming real human traffic (the 24h land:/ref: read).
