/**
 * KWC Card Grid — frontend styles.
 *
 * Defaults to the KWC brand tokens defined in the theme (--primary-font,
 * --brand-color-purple, --rps-color-gray-*, etc.). Every token has a
 * non-brand fallback so the block still works on pages where those
 * variables aren't loaded.
 *
 * All visual properties are CSS custom properties on .kwc-cg-wrap so
 * per-instance overrides (set as inline style by the render callback)
 * override the defaults cleanly.
