Replace the legacy mule-image backend with PhotoPrism plus a thin SvelteKit client and a Node sidecar for endpoints PhotoPrism doesn't expose (file rename), and add a two-phase migrator (metadata via PUT, heaps → albums) for the existing Postgres library.

/**

* Bounded concurrency keeps the indexer happy on slow hosts; each item's

* shape the legacy mule-image bulk endpoint returned, so existing toast
|
|
* + undo plumbing slots in without changes.
