/*
 * Selene Design System
 *
 * Foundation layer: tokens, base styles, layout container, buttons,
 * forms, and accessibility styles. Component styles live in style.css
 * and must consume these tokens — never redefine them.
 *
 * Breakpoints (CSS custom properties cannot be used in media queries,
 * so these values are fixed by convention — use them verbatim):
 *   sm  600px   large phones / small tablets
 *   md  768px   tablets
 *   lg  1024px  small desktops
 *   xl  1280px  desktops
