root 38bffa491c Initial commit: WH40K Points Comparator

- React + MUI DataGrid app with faction filter, search, change filter
- Biggest movers cards (drops/rises) scoped to current filter view
- Historical points graph modal (5 MFM versions: 1.14 → current)
- URL state sync (faction, dir, q params — shareable URLs)
- Grimdark favicon + OG embed image (Google Imagen)
- Multi-stage Dockerfile (node build → nginx serve)
- docker-compose.yml with Traefik + Cloudflare TLS
- Data pipeline: build_deduped_data.py merges PDF + live scrape
- Ynnari merged into Aeldari (shared codex)
- Mobile responsive: flex columns, no fixed pixel widths
- Color semantics: green=cheaper, red=costlier (consistent everywhere)
- 1,449 units across 31 factions

WH40K Points Comparator

Compare Warhammer 40,000 unit points across Munitorum Field Manual versions.

Features

Multi-version comparison — Track points changes across 5 MFM versions (1.14 → current)
Faction filtering — Browse by faction or view all 1,449 units
Biggest movers — Top 5 price drops and rises for the current view
Historical graph — Click any unit to see a points history chart across all MFM versions
Shareable URLs — Filter state is stored in URL query params (?faction=...&dir=...&q=...)
Mobile responsive — Flex-based layout that scales to any device
Social embeds — OG/Twitter meta tags with grimdark favicon and preview image

Tech Stack

React + MUI (Material UI DataGrid)
Vite build
nginx (Alpine) in Docker
Traefik reverse proxy with Cloudflare TLS

Data Sources

Current MFM — Scraped from warhammer-community.com (live data)
MFM 4.3 (Jun 2026), 3.2 (Aug 2025), 2.3 (Mar 2025), 1.14 (Dec 2024) — Parsed from PDFs

Deployment

Using Docker Compose (recommended)

Edit docker-compose.yml — change the Host() rule to your domain
Build and deploy:

docker compose up -d --build

Without Traefik

Uncomment the ports section in docker-compose.yml:

ports:
  - "8080:80"

Then access at http://localhost:8080.

Building from scratch

The Dockerfile is multi-stage:

Build stage — node:20-alpine installs deps and runs npm run build
Runtime stage — nginx:alpine serves the static files

No pre-built artifacts needed — just docker compose build.

Data Pipeline

PDFs + live scrape → per-faction JSON files
                         ↓
              build_deduped_data.py
                         ↓
              react-app/public/data.json
                         ↓
                   React app (fetched at runtime)

Run python3 build_deduped_data.py to rebuild data.json from source data.
