/* ============================================================================
 * kdCommun/css/forms.css
 * Design system partagé pour les éléments de formulaire kdFast.
 *
 * Pensé pour être utilisé conjointement avec modals.css : les classes de type
 * (.kdModalDanger / Primary / Success / Info / Warning) exposent les variables
 * --kd-accent / --kd-accent-strong / --kd-accent-bg / --kd-accent-shadow qui
 * sont consommées ici (focus inputs, gradients des boutons primary, etc.).
 *
 * Utilisable aussi en dehors d'une modale : un parent qui définit
 * --kd-accent suffit. Sinon, fallback violet par défaut.
 *
 * Usage minimal :
 *   <div class="kdFieldsRow row2">
 *     <div class="kdField">
 *       <label><i class="fa-solid fa-hashtag"></i> Numéro <span class="kdReq">*</span></label>
 *       <input type="text" name="num" required>
 *     </div>
 *     <div class="kdField">
 *       <label><i class="fa-regular fa-calendar"></i> Date</label>
 *       <input type="date" name="date">
 *     </div>
 *   </div>
 *
 * Boutons :
 *   <button class="kdBtn kdBtnSecondary">Annuler</button>
 *   <button class="kdBtn kdBtnPrimary">Valider</button>     (reprend l'accent du parent)
 *   <button class="kdBtn kdBtnDanger">Supprimer</button>    (rouge explicite)
