/*
 * toast.css — vanilla-JS port of Sonner stack/animation styles.
 *
 * Color, radius, typography, shadow tokens are deliberately not set here;
 * style via [data-sonner-toast] in the consumer's stylesheet. Variables
 * the toast layer needs (set by toast.js inline on each instance):
 *   --width, --gap, --front-toast-height, --initial-height,
 *   --index, --toasts-before, --z-index, --offset, --y, --lift,
 *   --lift-amount, --swipe-amount-x, --swipe-amount-y,
 *   --offset-top/right/bottom/left, --mobile-offset-top/right/bottom/left
 *
 * Selectors mirror Sonner so any override snippet from the Sonner ecosystem
 * applies cleanly.
