💳 Subscriptions, quotas, Google sign-in, geo-pricing
- Subscription via FunPay — 3 tiers: Free (30 msg/day), Basic (199 ₽/mo), Pro (499 ₽/mo). Buy → get key → paste into Settings → License. Verified offline (Ed25519).
- Geo-localized pricing on the site — detects your country from IP and shows prices in your local currency: RUB, USD, EUR, GBP, INR, TRY, CNY, BRL, UAH, PLN, JPY, KRW. "Show in ₽" toggle is always available.
- Quota enforcement — limits + model access are checked before every request. When exceeded, a dialog appears with a "Buy subscription" button.
- Sign in with Google — big white button on the login screen. Opens the browser, returns when done. Local email/password remains as a fallback.
- Removed "Continue as guest" — accounts only now.
- Pricing page on the site: /pricing — all tiers and activation steps.
- Backend API on Render — optional FastAPI service for auto-issuing keys after FunPay purchases. The site works without it.
- Scroll fix during streaming — you can now scroll back up to read while DeepSeek is writing, auto-scroll won't reset your position.
- $/M token columns removed from the site — API key is bundled; pricing is only visible in the in-app token counter.
