   input-button-native.css — Input com botao nativo (brand style, azul)
   ----------------------------------------------------------------------------
   Componente AUTOSSUFICIENTE: NAO depende do Tailwind JIT/CDN. Basta
   referenciar este CSS na pagina e usar a marcacao abaixo.

   USO SIMPLES (sem floating label):

     <div class="input-native-group">
       <input type="text" id="cep" class="input-native-input" placeholder="CEP">
       <button class="input-native-btn" title="Buscar">
         <i class="ti ti-search"></i>
       </button>
     </div>

   USO COM FLOATING LABEL (label flutua ao digitar):

     <div class="input-native-group">
       <div class="input-native-field">
         <input type="text" id="cep" class="input-native-input"
                placeholder=" " autocomplete="off">
         <label for="cep" class="input-native-label">CEP</label>
       </div>
       <button class="input-native-btn" title="Buscar">
         <i class="ti ti-search"></i>
       </button>
     </div>

   Regras:
   - Para floating label, o <input> PRECISA do placeholder=" " (um espaco).
     O CSS usa :not(:placeholder-shown) para detectar se ha valor digitado.
   - O <label> deve ser irmao do <input> dentro de .input-native-field.
   - Tema claro/escuro automatico via variaveis de variables.css.
