Sprint 2026-05-20 → 2026-05-21 — Billing end-to-end + landing 3D + pricing premium

Implementação completa das 3 fases do pricing (PRs A→B→C + UI), redesign da landing com 3D real CSS, reescrita do copy pra falar com lojista, premium positioning + páginas comparativas vs concorrentes.

Fase 1 do pricing (backend) — vek1#73 + vek1-api#24 + vek1-api#25

• vek1 #73 (eb74c26) Schema billing + Stripe seed + beta migration
  • 4 tabelas novas: subscription_plans, company_subscriptions, company_billing_settings, token_topups
  • Alter token_usage: +billable, +topup_id, +reported_to_stripe_at
  • Scripts: seed-stripe-plans.ts (idempotente, cria Meter + 3 Products + 6 Prices), migrate-beta-companies.ts (legacy → past_due)
  • Indexes em recreate-indexes.ts
  • Aplicado em prod (Postgres VPS + Stripe test mode)
• vek1-api #24 (7bf82e2) Billing service + endpoints + Stripe webhook
  • services/stripe_client.py singleton + services/billing_service.py com check_quota_or_block (state machine 3-day grace)
  • routers/billing.py (10 endpoints: plans, summary, subscriptions, setup-intent, topup, settings, invoices, debug triggers)
  • routers/stripe_webhook.py com signature HMAC validation pros 6 events
  • 25 service tests + 18 endpoint tests + 7 webhook tests + 4 E2E reais Stripe
• vek1-api #25 (660b739) /chat enforcement + apscheduler + emails Resend
  • services/chat_billing.py extraído (resolve_company_id, quota_block_response, record_token_usage)
  • services/billing_emails.py (cota_warning_80, grace_started, grace_expired, charge_succeeded/failed)
  • apscheduler in-process cron 5min reportando usage_record pro Stripe
  • 223 tests passing + 4 E2E

Fase 2 do pricing (frontend UI) — vek1#74

• vek1 #74 (b39a5d8) UI completa: /settings#billing + /pricing + signup wizard
  • apiClient.billing (10 funções tipadas)
  • app/actions/billing-actions.ts (server actions com validação)
  • BillingSection componente (planos + uso + cartão + topup + plan switch + invoices)
  • AddCardModal (SetupIntent + Stripe Elements)
  • TopupModal (PaymentIntent off-session ou Elements)
  • PlanCompareModal (3 tiers comparativos)
  • /pricing página pública com tiers + bônus 50% callout
  • /onboarding/billing wizard 3-step (plano → cartão → ativar)
  • company-registration.tsx redireciona pós-signup pra /onboarding/billing
  • Stripe Elements via @stripe/stripe-js + @stripe/react-stripe-js

Landing redesign + copy

• vek1 #75 (f66b8e6) Landing 3D Industrial Atelier
  • Substitui landing antiga (cards genéricos) por composição editorial maximalist
  • 3D real CSS (perspective + preserve-3d, sem Three.js)
  • Hero phone diorama com mouse parallax (pointermove → CSS vars)
  • 6 floating chips com --z translateZ + animation float-3d
  • Iso grid floor no backdrop
  • Pricing 3D (Pro elevated translateZ(35px))
  • TiltCards no features
  • Instrument Serif italic display + IBM Plex Mono labels
  • Helpers globais: .editorial, .iso-stage, .float-3d, .stencil, .glow-primary, .reveal-up
• vek1 #77 (afc...) Copy rewrite — remove jargão técnico
  • Status: "v3.0 · agentes RAG" → "ativo · pra lojistas no whatsapp"
  • Marquee: stack tech (deepseek, bge-m3, postgres…) → tipos de negócio (petshops, salões, padarias…)
  • Stats: stat fabricado "6.4× vs CRM" → value prop real "PIX confirmado direto no chat"
  • Features: "function calling" → "Não só responde — vende de verdade"
  • Reescrito tom: cliente PME, não dev
• vek1 #78 Hero 2-col + CTAs aware logged + /billing internal page
  • CTAs detectam sessão (logged → "Ir pro painel" / anon → "Criar conta")
  • Grid md:grid-cols-2 em vez de só lg+ (phone não sobrepõe texto em md)
  • Phone scene responsive: h-[400px] md:h-[460px] lg:h-[520px]
  • /billing página dedicada (era seção em /settings) + sidebar link
• vek1 #79 Comparativo + calculadora na /pricing
  • ComparisonTable 3-col (vek vs chatbot tradicional vs atendente humano) — não nomeia concorrentes
  • CostCalculator client interactive (salário CLT + headcount → economia)
  • Plano sugerido auto-pick

Pricing premium + páginas vs concorrentes

• vek1#80 Premium positioning (Stripe Prices v2)
  • Starter R$ 79 → R$ 199 / 500k → 1M tokens / overage R$ 25 → R$ 39
  • Pro R$ 299 → R$ 599 / overage R$ 18 → R$ 28
  • Business R$ 899 → R$ 1.499 / overage R$ 12 → R$ 20
  • Lookup keys versionados _v2 (Prices Stripe imutáveis); v1 antigos mantidos pra subs existentes
  • DB atualizada via SSH (script local timeout TCP firewall)
• vek1#80 Páginas SEO /pricing/vs/[slug]
  • lib/competitors.ts com 6 concorrentes: octadesk, socialhub, blip, zenvia, chatguru, wati
  • Dynamic route com generateStaticParams + generateMetadata SEO-otimizada
  • Cada página: cards lado-a-lado preço, 5 advantages, seção "quando faz sentido escolher X" (sinal de honestidade), calculadora reaproveitada, cross-links
  • Footer /pricing tem 6 chips discretos linkando pras vs pages

Fixes pricing infra

• vek1#76 Fallback hardcoded na /pricing quando DB inacessível
• vek1#81 Fail-fast 3s timeout (era 30s default) + console.warn (era error) — UX melhor em dev sem firewall liberado
• vek1-api #26 (b277363) Endpoint público /billing/plans-public — /pricing consome via HTTPS em vez de TCP direto Postgres
• vek1#82 /pricing migrada de Drizzle direto pra fetch via vek1-api — funciona em qualquer rede (HTTPS 443 nunca bloqueado)

Pequenos UX

• vek1#83 + vek1#84 /login e /register são páginas simples — removido redirect/banner quando logado (over-engineered)
