/*
 * Free Tools — shared design system.
 * Design tokens + primitive components (buttons, cards, fields, toast,
 * badges, accordion) used by every module. A module's own stylesheet should
 * only ever add layout for ITS shortcode markup — never redefine a button,
 * card, toast, or color here.
 *
 * Everything is scoped under .free-tools so it never leaks into (or is
 * fought over by) the active theme's global styles.
