Tips

• Refreshing the page often resolves stale data issues
• Check the browser console (F12 > Console) for detailed error information
• Worker logs can be viewed with: npx wrangler tail events-<slug>
• API errors follow the format { error: { code, message, details } }. The code is a stable identifier; the message is localized to the user's language
• Confirmation dialogs appear before destructive actions (delete, invalidate, cancel). They cannot be undone
