# The Vault

> **[INCOMING — Mission Control, Earth]**
>
> Cadet, every program needs to remember things. Variables hold
> values; types tell Python what kind of value:
>
> - `int` — whole numbers, like `3`
> - `float` — decimals, like `4500.5`
> - `str` — text in quotes, like `"Apollo"`
> - `bool` — `True` or `False`
>
> A **dictionary** maps keys to values. Implement a function `vault`
> that returns a dictionary with exactly these four keys and values:
>
> ```
> "mission":   "Apollo"
> "crew_size": 3
> "fuel_kg":   4500.5
> "ready":     True
> ```

## Your Task

Open `starter/starter.py`. Replace `pass` with `return { ... }`.

## Objectives

- `vault()` returns a dict
- Each key holds the exact value above (and the right type)
