/* =============================================================================
   Ela Design System — Field (labelled text input)
   -----------------------------------------------------------------------------
   The form-input counterpart to the chat composer (.input): a labelled, single
   control used in forms — sign-up, settings, profile. Shares the composer's
   surface language (bg-active fill, shine stroke, brand focus-ring) so forms and
   the composer read as one family, but adds a label, optional leading icon,
   hint, and an error state.

   Structure : .field › .field__label + .field__control(› .field__icon? +
               .field__input) + (.field__hint | .field__error)
   States     : .field--error · .field--disabled  (+ native :focus-within)
