Minimalist Flowchart Style Guide

Clean minimal e-commerce user journey process flowchart, pure #FFFFFF white background, no extra decorative elements, strictly follows the specified style guide:
Line and border color is dark gray #333333 or pure black #000000; all text is dark gray #333333, regular font weight, no bold; shape fills are either fully transparent or solid pure white to cover underlying lines.
All connecting lines are orthogonal elbow lines with only 90-degree right angle corners, 1px extremely thin thickness, line endpoints are equipped with solid small black triangle arrowheads.
Shape specifications: normal process nodes are rounded rectangles with 4-8px small corner radius, decision nodes are diamond-shaped, start and end nodes are capsule shapes with large rounded corners.
Typography rules: all text is center-aligned inside shapes, uses clean sans-serif font (Arial, Roboto, or Source Han Sans), 12-14px small font size.
The flowchart displays a logical user journey flow: Start capsule node "User Visits Store" -> rounded rect node "Browse Product Listings" -> diamond decision node "Find Desired Product?" -> Yes path rounded rect node "Add to Cart" -> rounded rect node "Complete Checkout" -> end capsule node "Order Confirmation"; No path rounded rect node "Use Search Function" -> loops back to "Browse Product Listings".
No extra shadows, gradients, or decorative elements, high resolution, sharp clear lines, no blurring.
