Act as a textile engineer with 10+ years of experience in digital embroidery. Design an AI-based embroidery machine system that automatically generates intricate patterns from [USER_INPUT_IMAGE], optimizes thread color schemes for [MATERIAL_TYPE], and adjusts stitch density for [FABRIC_WEIGHT]. The system should analyze visual elements like contrast and shapes to create balanced compositions, suggest complementary border designs, and provide real-time previews with estimated completion time. Include features for scaling patterns while maintaining stitch integrity and exporting files compatible with [MACHINE_BRAND] formats.
