UPLOAD OWNERSHIP
Bound the input.
Own the request.
Keep bounded state
The selected name, type, size, and text remain route-owned for retry without reselection.
Use native multipart
One owned effect reconstructs the Blob, FormData, fetch request, and abort signal.
Abort exact work
User cancellation and route departure release the same in-flight request owner.
Retain recovery input
Accessible transport feedback preserves the selected file state for direct retry.
Append the attachment
A successful response updates the existing keyed list with no transfer runtime.
UPGRADE
Keep upload ownership application-local.
