Function: createPreviewOffline()

createPreviewOffline(image, media): PreviewResult

Generate an offline preview without a live printer connection.

LabelManager is single-colour, so the result always contains a single black plane. The bitmap is rendered at the image's native resolution using Atkinson dithering (matching the DymoPrinter.print() rendering path); the preview consumer is responsible for scaling and cropping to match the selected tape width.
