/*
 * Chaza look & feel — "Ndebele Spark".
 * Inspired by the bold geometric wall art of the amaNdebele: cream walls, thick black outlines and
 * blocks of gold, red, blue and green. Original pattern work (no copied artwork).
 * Mobile-first, no external dependencies, WCAG AA contrast targets, dark mode, reduced motion.
