/**
 * @file components.css
 * @description Reusable Nova Soul UI components (v0.1). Copy the markup from
 * index.html (the style guide) and these classes work on any page.
 *
 * Depends on: css/tokens.css, css/base.css.
 * Loaded by: every HTML page.
 * Behaviour: js/app.js (language switch, price sync), js/i18n.js (texts).
 *
 * Naming: .ns-block, .ns-block__element, .ns-block--variant.
 * Each component sets only its own internals; spacing BETWEEN components
 * belongs to the page layout, which prevents specificity fights.
