v1.5.0

Added

• Persist Fabric canvas dimensions in editor history snapshots so undo and redo restore layout size after rotate, scale, crop, merge, and mask expansion workflows.
• Add full canonical DOM binding keys for the 1.x line, using semantic names such as imagePlaceholder, scalePercentageInput, rotateLeftDegreesInput, removeSelectedMaskButton, downloadImageButton, and enterCropModeButton.

Changed

• Keep deprecated DOM binding keys with *Btn names as explicit 1.x aliases with one-time migration warnings.
• Update the docs demo and README examples to use canonical DOM binding keys.

Fixed

• Block non-crop programmatic operations while crop mode is active while keeping applyCrop() and cancelCrop() available.
• Harden reset, image-load rollback, Fabric state restoration, animation queue cancellation, and crop failure paths against partial state updates.
• Clean up mask and crop event handlers on removal and disposal, restore captured canvas maxWidth, and tolerate missing drag-and-drop dataTransfer in the docs demo.
