// NOTES
//
// The global config SHALL NOT be used to set defaults for Boolean props, as the props
// would loose their semantic meaning, and force people writing 3rd party components to
// explicitly set a true or false value using the v-bind syntax on boolean props
//
// Supported config values (depending on the prop's supported type(s)):
// `String`, `Array`, `Object`, `null` or `undefined`
// BREAKPOINT DEFINITIONS
//
// Some components (`<b-col>` and `<b-form-group>`) generate props based on breakpoints,
// and this occurs when the component is first loaded (evaluated), which may happen
// before the config is created/modified
//
// To get around this we make these components' props async (lazy evaluation)
// The component definition is only called/executed when the first access to the
// component is used (and cached on subsequent uses)
// PROP DEFAULTS
//
// For default values on props, we use the default value factory function approach so
// that the default values are pulled in at each component instantiation
//
//  props: {
//    variant: {
//      type: String,
//      default: () => getConfigComponent('BAlert', 'variant')
//    }
//  }
//
// We also provide a cached getter for breakpoints, which are "frozen" on first access
// prettier-ignore
