Keep everything before the vertical bar (|) as is, including the vertical bar. Translate the tab title. Translate the tab content, applying the rules you know. Keep the four block closing slashes as is.

Examples:

Because we are passing it as a **value to an argument** instead of putting it in a **type annotation**, we have to use `Union` even in Python 3.10.

If it was in a type annotation we could have used the vertical bar, as:

```Python
some_variable: PlaneItem | CarItem
```

You can declare that a variable can be any of **several types**, for example, an `int` or a `str`.

To define it you use the <dfn title='also called "bitwise or operator", but that meaning is not relevant here'>vertical bar (`|`)</dfn> to separate both types.

This is called a "union", because the variable can be anything in the union of those two sets of types.

//// tab | Info

Tabs and `Info`/`Note`/`Warning`/etc. blocks should have the translation of their title added after a vertical bar (`|`).

See sections `### Special blocks` and `### Tab blocks` in the general prompt in `scripts/translate.py`.
