Fanout Bundle Plus Spurs

Gallery / Feature Showcase

A shared source fans out three ways at once: a same-column multi-line branch wrapping to the row below, plus single-line spurs peeling off the same junction. The branch bundle keeps its concentric fan order, each spur's descent fuses onto the bundle rather than crossing it, and the single-line spur sections ride their own trunks.
