/* ============================================================
   NiCE Brand Primitives — logo lockup, smile, chat bubbles,
   squircles, gradient surfaces, buttons.
   Depends on colors_and_type.css (load it first).

   NOTE: official NiCE wordmark artwork now lives in /assets/logo
   (SVG + PNG, black/white ± blue dot) — prefer <img src> to that for
   any real use. The .nice-logo CSS below is a lightweight text
   fallback only.
