v1.4.2

Added

• Add a public isBusy() helper so demo integrations can avoid private loading and crop state.

Fixed

• Preserve selected mask labels, editable mask styling, and active selection after both merged and plain exports.
• Validate custom fabricGenerator results before applying mask setup, returning null with a warning instead of throwing a raw TypeError.
• Reject broken restored image elements instead of treating a completed zero-dimension image as ready.
• Clamp the crop rectangle inside the image bounds during move and resize operations.
• Roll back crop state when mask preparation fails before crop export.
• Decode exported files without requiring a global atob, and handle more transparent CSS background forms before JPEG compositing.
• Guard invalid downsample dimensions and remove stale load-rollback state captured during image replacement.
• Use a global internal operation token so duplicate module evaluations do not break merge-owned load calls.
• Keep the docs demo busy-state checks on public API, clear successful Base64 loads, and align follow-up UI refreshes with the configured animation duration.
• Declare Fabric as a dev dependency as well as a peer dependency so local production audits do not treat the test peer install as runtime package surface.
