A modern UI/UX design screenshot of a professional data pipeline workflow tool. The color palette is clean white for the background, creating a high-legibility interface. Text is a crisp, deep black. Sophisticated orange is used for all interaction elements: buttons, active tab indicators, data stream arrows, and key icons. The central part of the screen displays a series of distinct, well-defined vertical cards representing workflow stages. Each stage (e.g., Data Ingestion, Transformation, Enrichment, Validation) has an accent orange left border and features clear, orange-colored data-centric icons. Subtle gray lines are used for grid structure. Modern, legible sans-serif font face. Legible text elements like "WORKFLOW: Apple POI Conversion", "STAGE 1: Ingest Data", "STAGE 2: Map Fields", "STAGE 3: Enrich Data". A clean top bar has a status section with an orange tag. The overall impression is efficient, logical, and trustworthy.
