how it works

1. enter a 17-character vin (e.g. MAT629103K1H01674)
2. first 3 chars (wmi) identify the manufacturer
3. manufacturer lookup tables decode year and month
4. results shown instantly in a card layout

handles 6 year-encoding types and 5 month-encoding types:

encoding	used by
year type 1 (a-t → 2010-2030)	tata, honda, mahindra, hyundai, etc.
year type 4 (2-digit → 2010-2030)	volkswagen, skoda, toyota
month type 1 (a-p → jan-dec)	tata, honda, hyundai
month type 5 (1-c → jan-dec)	nissan, renault

known limitations

• no support for older maruti suzuki (pre-2010 encoding)
• vw/skoda share MEX after 2021 (ambiguity)
• ford month encoding not fully implemented
• decodes manufacturer, year, month only — not plant/serial

see open issues for planned work.
