RTL support

Arabic (ar) uses a right-to-left layout. All other languages use left-to-right.

How language is detected

TREK resolves the display language in this order:

1. User preference — the language saved to your account (set in Settings → Display).
2. Browser language — navigator.languages (and navigator.language) reported by your browser.
3. Server default — the DEFAULT_LANGUAGE environment variable set by the admin.
4. Fallback — English (en).

Where the language picker appears

• Login / Register page — before you are signed in.
• Settings → Display — after you are signed in. See Display-Settings.
• Public share pages — trip share links.
• Public journey pages — public-facing journey views.

Admin: The DEFAULT_LANGUAGE environment variable sets the fallback language shown on the login page and for unauthenticated users. See Environment-Variables.
