Detailed Description

Direction-only flow-arrow sublayer — style bag + sublayer plumbing.

    The QSG geometry for this sublayer is built inside
    SWMM2DResultsQSGRenderer (same pattern as ContourBand/Isoline),
    which has direct access to the cell-centered velocity field and
    the dry-depth mask. buildOrUpdateNode() therefore returns the
    existing node unchanged.
