⚠️ Potential issue

Complete number translations for all values.

The number translations section is missing values between decades (21-29, 31-39, etc.). These are needed for complete number formatting support.

Please add the missing number translations. The current implementation will fail for numbers like 45, 67, etc.

Consider using a number composition system:

"number_composition": {
  "connector": "و",
  "format": "{tens} {connector} {ones}"
}
