/*!
 * Devlys to Unicode Converter — front-end styles
 *
 * Every rule is scoped under .dtuc-wrap so this plugin never touches
 * the rest of your WordPress theme (no global resets, no bleeding
 * button/input styles). Written by hand in a Tailwind-style utility
 * methodology (small, single-purpose custom properties + classes)
 * instead of loading the full Tailwind CDN build, which injects a
 * global CSS reset that can visibly break themes and adds ~300KB of
 * JIT-compiler JavaScript that has to run on every page load. This
 * file is a few KB and does nothing outside its own container.
