Clients navigate a three-step wizard (overview → tier selection → summary + accept), provide optional email/notes, and immutably confirm acceptance.

All three tasks completed without deviation. + +## Key Decisions Made + +1. **Rate Limiting Strategy**: Used existing `rateLimit()` utility instead of creating new `checkRateLimit()`. Function signature more flexible (key, limit, windowMs) and already battle-tested in codebase. + +2. **Proxy.ts Integration**: Integrated rate limiting into existing `proxy()` function (Next.js 16 pattern) rather than creating separate `middleware.ts`. Maintains single point of entry for all route guards. + +3. **Step Navigation**: Pure state-based navigation in QuoteMultistep (no React Hook Form for wizard). Each step is independent component receiving quote data as prop. Reduces complexity for MVP (no shared form state across steps). + +4. **Success State UX**: After acceptQuote success, render thank-you screen in Step3Summary component (no redirect). Provides reassurance to client that acceptance was recorded and next steps. + +5. **Immutability Enforcement**: Database-level check in server action confirms `accepted_at IS NOT NULL` before update, preventing double-accept. This aligns with CLAUDE.md constraint that accepted_at is immutable once set. + +## Tech Stack + +**Added:** +- shadcn/ui components: Button, Card, Input, Label, Textarea +- Lucide icons: ArrowRight, ArrowLeft, CheckCircle, X +- Next.js 16 proxy pattern for middleware +- Server actions for acceptQuote/rejectQuote with Zod validation +- Drizzle ORM update with returning() for atomic transaction +- revalidatePath() for cache invalidation + +**Patterns Used:** +- Public token-gated routes (no Auth.js required) +- Rate limiting at middleware level (3 requests/minute per IP) +- Multistep form component with visual progress indicator +- Server action with immutability guard (check before update) +- Graceful error handling with Italian localization + +## Known Stubs + +**1.
