Extend the existing dark teal stroke continuously from the upper tip of its short lower-left starting segment, following the already visible connected guide: up the left segment, along the rising diagonal to the top, down the right diagonal, then down the final right segment. Previously darkened portions remain dark and in place. Advance one connected drawing front; do not darken disconnected distant segments at the same time. Do not add a pen, hand, lettering, extra branch, second line or moving background. Finish when the original guide is covered by the same single dark stroke, then hold. Do not replace the path with another icon or cut directly to a finished drawing.",
