/**
 * Clamp ONE side's raw band thickness (Σ of the side's RAW link thicknesses) to
 * the visible band height used for the node shape.
 *
 * @param raw_band     Σ of the RAW (proportional, non-floored) thicknesses of the
 *                     side's sizing links. Sub-pixel/structural flows contribute
 *                     < minimum_flux / 0 here because they overlap at the anchor.
 * @param has_links    whether the side carries at least one sizing link. An empty
 *                     side returns 0 so the caller's shape_min_height governs
 *                     (preserves the pre-#201 behaviour for link-less sides).
 * @param minimum_flux drawing area floor; falls back to the 2px hard floor when
 *                     unset, mirroring Class_LinkElement._clampThickness.
 *
 * The maximum_flux cap is intentionally NOT re-applied here : each link's raw
 * thickness is already capped at maximum_flux upstream (Link._safeRawThickness),
 * so capping the band sum again would wrongly shrink a legitimately tall node.
