/* ==========================================================================
   FORM FIELDS — generic, reusable input/select/textarea primitives
   No such component existed in the theme prior to the Contact Us page
   (only the narrow single-purpose .du-search-field__input and
   .du-newsletter__input). Built from the same tokens those use
   (--surface, --border, --radius, --transition-fast) so it matches the
   existing visual language and is safe to reuse on any future form.
