/**
 * 🌿 Async source for loading items into Quay.
 * - crawlable and callable by the ui
 * - the functions provided are available for the ui user
 * - as we crawl, every item we see is cached for sync rendering
 * - minimal so as to be compatible even with raw opfs
 * - Opfs, Cellar, etc, will literally provide Twig implementations
