- Added getPathWithoutLocale() and buildLocalePath() helpers to locales.ts - Updated Header to use centralized helpers instead of hardcoded regex - Updated middleware to use SUPPORTED_LOCALES in matcher config - Updated LocaleProvider to use isValidLocale() instead of hardcoded array To add a new language now, only update: 1. SUPPORTED_LOCALES in locales.ts 2. LOCALE_CONFIG entry with label, flag, saleorLocale 3. Add translation keys to all message files All routing now uses centralized constants - no more hardcoded locale lists.
