Vale construir sua versão de tcgevents?

Build a local-first trading card game event tracker. Single Python project, no accounts, no cloud, no telemetry.

Stack, non negotiable:
- Python 3.11, FastAPI, Jinja2 templates, SQLite via sqlite3 stdlib
- Plain server rendered HTML plus a little vanilla JS, no build step, no npm
- Leaflet from a CDN for the map, OpenStreetMap tiles

Data model (events): id, game (magic, pokemon, yugioh, lorcana, other), title, format, venue_name, address, city, country, lat, lon, starts_at (UTC), ends_at nullable, entry_fee nullable, url nullable, notes, source (manual or paste), created_at, updated_at.
Also a settings row for home_lat, home_lon, default_radius_km.

Features, in scope:
1. Add and edit events through a simple HTML form. Manual entry is the primary path, treat it as first class.
2. A "paste dump" page: textarea where I paste messy text from a store Discord or Facebook post, plus a parser that extracts candidate title, date, time and fee with regex and dateutil, then shows an editable pre-filled form. No LLM call. If parsing fails, say so and let me fill it in.
3. List view: filter by game, date range, city, and distance from home using haversine on stored lat/lon. Sort by starts_at.
4. Map view: pins for filtered events, popup with title, time, venue, link.
5. Calendar: current month grid, events per day.
6. Export: /export.ics returns a valid VCALENDAR of the current filter. Also /export.json.
7. Geocoding: optional. If GEOCODE_PROVIDER and GEOCODE_API_KEY are set in .env, geocode addresses on save; otherwise leave lat/lon null and hide distance filters gracefully.
8. Recurring events: a weekly repeat option that materializes the next 8 occurrences, each editable and cancellable individually.

Out of scope, do not build: user accounts, multi tenancy, scraping any third party site, push notifications, a mobile app, anything that pretends to have nationwide coverage.

Deliverables: app.py, db.py, parse.py, templates/, static/, schema.sql, .env.example, seed.py with 12 fake events across 3 cities, and a README with run instructions (uvicorn, one command). Include pytest tests for the parser and the ICS output. Timezones: store UTC, display in a TZ set in .env, default America/New_York.
