/* ============================================================================
   refresh-forms.css: the rf- form design system (spec 006, research R2).
   Net-new design work — the reference build contains no forms — built from
   the rf- token system so fields sit indistinguishably beside .rf-btn-primary
   and the resources-family paper/card patterns. Also skins the ASP.NET
   validation hooks (input-validation-error, field-validation-error,
   validation-summary-errors) so server-rendered errors get the same finish.
   Errors are never color-only: 600-weight text plus a badge icon (a11y).
