   forms — input · textarea · select · checkbox · radio · switch · chip ·
           file-drop · fieldset · form-field · error summary

   Rules encoded here, each one fixing a specific failure on the old site:
   • Labels ABOVE the field, always visible. Never placeholder-as-label.
   • Required is marked with the WORD "required", not only an asterisk.
   • Max field width 480px — a full-width text input invites a wrong answer.
   • Validation happens on BLUR, never on keystroke (see scripts/forms.js).
   • Every control has a real name, an autocomplete token, and HTML-level
     type/inputmode/required so validation works with JS disabled.
   • No control is 44px or smaller in its hit area.
