<li>Shortcode <code>[cal24h]</code> supporting attributes for iframe or floating-button display modes.</li>
<li>Settings page (<code>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Cal24h</code>) to define default values such as organization slug, event slug, language, and colors.</li>
<li>Theme personalization parameters for the stepper (primary colors, step labels, card backgrounds, stepper background).</li>
<li>Responsive floating button that opens a customizable modal overlay.</li>
<li>Ready-to-ship translations and language loading for both editor and front end. Included locales: ar, bn_BD, da_DK, de_DE, el, en_US, es_ES, fa_IR, fi, fr_FR, he_IL, hi_IN, id_ID, it_IT, ja, ko_KR, nb_NO, nl_NL, pa_IN, pt_BR, pt_PT, ru_RU, sv_SE, sw, tr_TR, ur, wo, zh_CN.</li>
<li>Paste-friendly slugs: you can paste a full Cal24h URL (e.g., <code>https://cal24h.com/integration/org/event</code>) into settings or shortcode attributes — the plugin extracts the correct organization/event automatically.</li>
