What to notice while you play.

Objective

Edit a fake file, save it, and verify the saved content.

Hint

The nano panel is fake, but the save writes to local browser state.

Why it matters

Reading back changes is a simple habit that prevents confusion.

Common mistakes
  • Forgetting to save before closing.
  • Editing a path whose parent folder does not exist.
