   Public API: <div class="iz-field"> wraps a label, a control
   (.iz-input / .iz-textarea / .iz-select — see input.css, select.css),
   and an optional .iz-field__hint or .iz-field__error. State
   (disabled, readonly, required, aria-invalid) lives on the control
   itself via native/ARIA attributes — this file has no .is-* classes.
