/* =========================================================
   NextIce Design System
   Concept: "Cut Ice" — precision, clarity, cold engineering.
   A single recurring signature motif — a clipped corner,
   like a facet cut into ice — appears on cards, buttons,
   images and the nav mark instead of rounded corners.
