withStepperConnectors

Description#

Opt the classic <cngx-stepper> skin into the connector-rail presentation: a solid completed/upcoming rail between adjacent step indicators, horizontal and vertical, with per-segment coloring driven by the preceding step's [data-state]. The rule is double-scoped on [data-skin='classic']; the four other skins each ship their own inter-step decoration and ignore this flag. Per-instance [connectors] Input still wins.
