How this works
- Config files live in voyage-configs/weather/<slug>.json — area, description, and list of product URLs to snapshot.
- npm run voyage refresh <slug> downloads every product into public/weather/voyages/<slug>/<YYYY-MM-DD>/.
- The voyage page shows the latest snapshot, grouped by category, with freshness timestamps.
- When you go offshore and lose connectivity, the saved images keep working — they're part of the static build.
- Re-run the refresh each morning on home wifi (or any internet) to get fresh charts.
