## FAQ
### Why straight-line distance?
It avoids routing-API costs and rate limits while still giving a defensible apples-to-apples ranking. The 30 mph average is calibrated to door-to-door drive time for the median US metro.

### Do you support international zip codes?
Not yet. The built-in lookup covers top US metros only — non-US codes are silently skipped.

### How accurate is this?
Within ~15% on average for US metros. For final selection, validate with Google Maps or a commute survey.

### Can I upload a CSV?
Paste CSV-style text (zip codes separated by commas or new lines) directly into the box. Excel and Google Sheets columns paste cleanly.
