 * Juno's type system - an extended Zod instance for Serverless Functions.
 *
 * The schema builder exposes all Zod schemas and functions aside from
 * `union()` which can't be reliably serialized currently without a discriminator field.
 * That's why you should prefer using `discriminatedUnion()` instead.
 *
 * It extends Zod with various schemas useful for writing your custom functions
 * such as `j.principal()` and `j.uint8Array()`.
 *
 * @example
 * import { j } from '@junobuild/schema';
 *
 * const MySchema = j.strictObject({
 *   id: j.principal(),
 *   name: j.string(),
 * });
