# CoFi Registration App

## Overview
Standalone event registration + payment app for CoFi (Collaborative Finance).
Adapted from `crypto-commons-gather.ing-website` with centralized config.

## Architecture
- **Stack**: Next.js 16 (App Router, standalone) + Mollie + Google Sheets + Mailcow SMTP + Listmonk
- **Deploy**: Docker on Netcup with Traefik labels
- **Key pattern**: All event-specific config centralized in `lib/event.config.ts`

## Flow
1. User fills `/register` form → POST `/api/register` → Google Sheets (Pending)
2. User picks accommodation/payment → POST `/api/create-checkout-session` → Mollie redirect
3. Mollie webhook POST `/api/webhook` → verify payment → assign booking → update sheet → email → Listmonk

## Key Files
- `lib/event.config.ts` — **Edit this to configure a new event** (pricing, dates, venues, branding)
- `lib/mollie.ts` — Shared Mollie client singleton
- `app/globals.css` — Blue/teal OKLch color theme
- `docker-compose.yml` — Traefik-labeled deployment

## Dev Workflow
```bash
pnpm install
pnpm dev          # localhost:3000 → redirects to /register
```

## Deployment
```bash
docker compose up -d --build
```
Traefik auto-discovers via labels. Update Host rule in `docker-compose.yml` for your domain.
