/*
 * Ezone UI v1 — components. Requires tokens.css. Style guide with markup: https://ezone.vn/ui/
 *
 * Every class starts with "ezu-" so it never collides with Bootstrap or an app's own classes
 * (POS already uses "ez-*"). Nothing here styles bare elements; opt in per element, or put
 * .ezu-page on <body> for the shared background and type.
