+- **Built comprehensive API documentation page** at `/docs` — 8 sections covering auth, all endpoints, request/response examples, error codes, common mistakes
+- **Fixed Stripe crash-on-startup** — Stripe SDK crashed when STRIPE_SECRET_KEY was empty. Changed to lazy initialization so app starts without Stripe configured.
+- **Fixed deployment flow** — rsync was deleting `.env` on server; added `--exclude .env` to preserve credentials across deploys.
+- **Updated all docs links** — landing page "View Docs" → `/docs`, signup response, billing success page all point to proper docs
+- **Full QA pass verified:**
+  - Health ✅ | Landing page ✅ | Docs page ✅
+  - Free signup ✅ | HTML→PDF ✅ | Markdown→PDF ✅ | URL→PDF ✅
+  - Templates list ✅ | Invoice template ✅ | Stripe checkout ✅
+  - Error handling (no auth, bad key, missing params) ✅
+- **Phase transition: Phase 1 → Phase 2** — product is polished and ready for customers
+- **Status:** All QA checklist items pass. Ready for marketing and customer acquisition.
+- **Next:** SEO, content marketing, dev community outreach, get first paying customer
