/* Referral Trust Banner
   Shown when a visitor lands via a referral link (cookie OR utm_medium=r).
   Reassures: "your free month is registered, sign up normally and it applies."

   Brand-system aligned: Rubik, brand gradient, pill dismiss button.
   Slim — does not push the hero down jarringly. Sticky at top, dismissable. */
