Hosts that want to show their own progress, upload the file or cancel can't use export(): it always downloads and draws its own overlay. exportBlob({ signal, onProgress }) resolves with the MP4 Blob and draws nothing. export(filename, fps) keeps its signature and behaviour and runs on the same private engine. Aborting rejects with ExportError phase cancelled, and ExportError is exported from the package root.

# PR Adds Why separate
1 (this PR) #224 exportBlob as the export engine The new API
2 #225 Pre-flight issues; fail on placeholders Routing depends on it
3 #226 Off-screen frames Stops the page jumping
4 #227 Clip speed in frames and audio Its own fix
5 #228 Size and bitrate from the edit Its own fix
6 #229 Refuse or correct the remaining wrong exports Found in the whole-stack review
7 #230 Release 2.26.0 Mechanical

Verify: npm run verify:ci; tests/export-coordinator.test.ts covers progress, abort before and mid-export, and export() still downloading.
