Once

Once blocks ensure content only appears during the first visit to a node. Returning to the node later skips this content.

Steps:

1. Write <<once>>
2. Write the content that should only appear once
3. Write <<endonce>> to end the block

Example:

title: TownSquare
---
<<once>>
This is your first time seeing the town square.
<<endonce>>
You stand in the town square.

This prevents repetition when players revisit locations.
