  <item>RFC-1191: initial parser test.</item>
  <item>RFC-1198: cookie-free referral attribution — /r/<slug> partner landings + voluntary referrer field

Replace the RFC-1191 wg_ref cookie capture with URL+form attribution:
static /r/<slug> and /<lang>/r/<slug> partner landings (noindex, zero JS,
consent-gated via publicNameConsentRef), ?ref prefill on the existing
referrerField rail, server-side slug resolution against the bundled
partners.yaml, referral_partner_slug/name on the Lagebild ingress contract,
legacy /?ref -> /r/<slug> 302 in the generated worker, and full removal of
the cookie capture module (wg_ref, referral.attribution entitlement,
payload.attribution).</item>
