/* ==========================================================================
   FORMULARIOS DEL SITIO PÚBLICO (#346)
   Componente del núcleo, como .btn: lo usan todos los formularios públicos
   (checkout, reservas, contacto...). El módulo solo pone la distribución de su
   página; los campos se ven igual en todo el sitio y siguen el tema (--color-*).

   <div class="form-row">                      dos columnas; una en el celular
     <div class="form-field">
       <label class="form-label" for="x">Nombre</label>
       <input class="form-input" id="x" aria-invalid="true">   (también select y textarea)
       <p class="form-hint">Ayuda opcional</p>
       <p class="form-error">El error del campo</p>
     </div>
   </div>
   <label class="form-check"><input type="radio" name="r"> Retiro en tienda</label>
