/* Honeypot field — issue #193 layer 3. Deliberately NOT display:none/visibility:hidden.
   UNVERIFIED: the claim that a form-filling engine or crawler can detect those computed
   styles and skip the field outright — which would turn a legitimately-skipped honeypot into
   a false "the caller never rendered the page" signal instead of a true "a human correctly
   ignored it" one — is the stated design rationale, not a claim cited against a vendor
   source. Pushed off-screen instead, so its layout box exists and its computed style reads as
   an ordinary (if oddly positioned) visible element, while a sighted user never sees it —
   see wwwroot/signup.html for the aria-hidden/tabindex/autocomplete layers that keep it out
   of a screen reader and the Tab order too. */
