/// Foundry configuration
///
/// # Defaults
///
/// All configuration values have a default, documented in the [fields](#fields)
/// section below. [`Config::default()`] returns the default values for
/// the default profile while [`Config::with_root()`] returns the values based on the given
/// directory. [`Config::load()`] starts with the default profile and merges various providers into
/// the config, same for [`Config::load_with_root()`], but there the default values are determined
/// by [`Config::with_root()`]
///
/// # Provider Details
///
/// `Config` is a Figment [`Provider`] with the following characteristics:
///
///   * **Profile**
///
///     The profile is set to the value of the `profile` field.
///
///   * **Metadata**
///
///     This provider is named `Foundry Config`. It does not specify a
///     [`Source`](figment::Source) and uses default interpolation.
///
///   * **Data**
///
///     The data emitted by this provider are the keys and values corresponding
///     to the fields and values of the structure. The dictionary is emitted to
///     the "default" meta-profile.
///
