Upload a large asset to Bynder programmatically using the chunked FS upload flow rather than a single request

Steps
Obtain an OAuth2 access token (or permanent token) with upload permissions before starting the upload flow
Split the file into chunks and upload each chunk with CORS-enabled requests directly against the designated upload storage endpoint returned by Bynder's upload initiation call
Register each successfully uploaded chunk with Bynder so the server can track upload progress and completeness
Send a 'finalize' request once all chunks have been uploaded and registered, signaling that the file is complete
Send a 'save' request to persist the finalized file as an asset within the target Brand/Bynder account, optionally attaching metaproperty values or tags at save time
Poll or listen for the resulting asset/media ID before assuming the asset is fully processed and available
Known gotchas
Respect Bynder's documented per-upload limits (a cap on the number of assets per batch upload and a maximum single-file size) — exceeding them causes uploads to fail rather than degrade gracefully
When uploading via the API, image dimensions are also capped (neither width nor height may exceed a fixed pixel limit), which differs from what the web upload UI may otherwise tolerate
Skipping the finalize/save steps after chunk upload leaves orphaned partial uploads that never become visible assets in the Bynder library
