What to include

If you're reporting a bug, it helps to include:

• What page or puzzle you were on (a shared puzzle link, if relevant).
• What you expected versus what happened.
• Your browser and device, if it looks visual (layout, rendering, touch targets).

Factual corrections

If something in a guide or technique page is wrong, say which page and what's inaccurate — these get corrected directly, not just noted.
