      <img src="/logo-oscuro.svg" alt="Logo" class="h-20 hidden dark:block mx-auto">
    </template>

Description

this line prevents for show the leading if none of the title props is set :
<div v-if="icon || !!slots.icon || (title || !!slots.title) || (description || !!slots.description) || !!slots.header" :class="ui.header({ class: props.ui?.header })">
Fix with an <div v-if="icon || !!slots.icon || (title || !!slots.title) || (description || !!slots.description) || !!slots.header || !!slots.leading" :class="ui.header({ class: props.ui?.header })">
