/*
 * Professional Image Converter — front-end styles
 *
 * Every selector is prefixed with `ic-` and scoped inside `.ic-root` so the
 * plugin can never leak styles onto (or collide with) the surrounding
 * theme or other plugins. No generic selectors like .container/.button
 * are used anywhere in this file.
 *
 * Design tokens are declared as CSS custom properties on .ic-root so the
 * whole tool can be retheme'd from one place without touching markup.
 * Font stacks are system fonts only — the plugin makes zero external
 * network requests, in keeping with its privacy-first positioning.
