Added a `ZoomStepPercentage` property to `PdfViewerOptions` to allow configurable zoom step increments (1-50, default 5%). Updated `EnvelopeViewer.razor` to use this property for the zoom slider step. Modified `pdf-viewer.js` to apply the zoom step percentage for mouse wheel zoom, `zoomIn`, and `zoomOut` methods. Included `ZoomStepPercentage` in `appsettings.json` and `setQualityOptions` for dynamic updates. Reduced `ZoomTransitionDuration` in `appsettings.json` from 900ms to 150ms for faster zoom transitions. These changes ensure consistent and customizable zoom behavior across the application.
