/* ============================================================
 * TEDDY DS — FORM
 *
 * Sistema de campos com a família `field-*`. Convive com o legado
 * `.form-group` de original.css (mantido para retrocompat).
 *
 * Anatomia:
 *   <div class="field">
 *     <label class="field-label">Nome <span class="field-required">*</span></label>
 *     <input class="field-input" type="text">
 *     <p class="field-helper">Como você quer ser chamado</p>
 *   </div>
 *
 * Variantes:
 *   <input class="field-input">         text/email/password/number…
 *   <textarea class="field-textarea">   …
 *   <select class="field-select">       …
 *   <label class="field-check">…</label> checkbox custom
 *   <label class="field-radio">…</label> radio custom
 *   <div class="field-search">…         input com ícone
 *
 * Estados (modificadores):
 *   .field.is-error      — destaca tudo em vermelho
 *   .field.is-disabled   — visual desabilitado (também aceita atributo disabled)
 *   .field-input.is-sm   — versão compacta
