Before Reporting

🔄 Try refreshing first

A hard refresh (Ctrl+F5 or Cmd+Shift+R) fixes many display issues caused by cached files.

📱 Try another browser

If the issue only appears in one browser, mention that — it helps us identify compatibility issues.

📋 Be specific

The more detail you provide — exact inputs, what you expected, what you got — the faster we can fix it.
