<?php

/**
 * Plain-PHP fallbacks for mb_* functions when mbstring extension is missing.
 *
 * These handle ASCII correctly, which is sufficient for the framework's
 * internal use (route matching, snake/camel case, validator attribute parsing).
 *
 * WordPress already polyfills mb_strlen and mb_substr via wp-includes/compat.php.
 * This file covers the remaining functions the framework and plugin use.
 *
 * When mbstring IS loaded, this file does nothing.
