Bulk update / API support for asset references across Replo pages

We are migrating away from Contentful and need to update hundreds of image and video references across Replo pages, templates, sections, and components.

Currently, it appears these references need to be updated manually in the Replo editor. It would be very helpful to have a way to perform bulk updates, ideally through one or more of the following:

• Project-wide search and replace for URLs

• Import/export of Replo page data in a structured format

• An API for reading and updating Replo page/template content

• A bulk asset migration tool that accepts an old URL → new URL mapping

Our specific use case is replacing Contentful asset URLs with Shopify CDN URLs, but this would also be useful for any CDN migration or large-scale asset reorganization.

Ideally, the replacement would update the underlying Replo source so that future edits and republishes preserve the new asset references.
