feature: /json-to-jsdoc

# The Big Idea

I'd like to host a standalone online tool like https://transform.tools/json-to-jsdoc, but that will break down intermediary types, and also handle enums.

- [ ] JavaScript conversion function (no frameworks or libraries)
- `JSON.stringify(input, null, 2)` to prettify JSON
- Traverses JSON to produce JSDoc
- Checkbox for "treat arrays as enums"
- Order types alphabetically
- "" is type `String`
- "a|b|c" creates a typedef `MyTypeStatusEnum` ?
- [ ] HTML Textareas
- CSS with variables (see MVP.css)

## Example Output: JSON

```js
/** @typedef {object} json
* @property {object} about
* @property {string} about.legalBusinessName
* @property {string} about.website
* @property {string} about.industry
* @property {string} about.countryOfOperation
* @property {string} about.description
* @property {string} about.operations
*/
```

should instead be

```js
/**
* @typedef MyType
* @prop {MyTypeAbout} about
*/

/**
* @typedef MyTypeAbout
* @prop {String} legalBusinessName
* @prop {String} website
* @prop {String} industry
* @prop {String} countryOfOperation
* @prop {String} description
* @prop {String} operations
*/
```

## Example Output: Enums

Maybe any props that are all caps and assigned an array could be considered enums?

```js
/**
* @typedef {"IsPep"|"IsNotPep"} PepOption
*/
Mercury.POLITICALLY_EXPOSED_OPTIONS = ["IsPep", "IsNotPep"];
```

No files, tests, or entry points are named. Start by locating the standalone tool's JavaScript conversion code and HTML textarea UI, then compare the implementation with the requested intermediary types, enum handling, alphabetical ordering, and CSS variables; completion means the listed JSON and enum examples produce the intended JSDoc output.
