/* Bingo Trợ giảng AI on flyer.vn/home-v6/ (02/11/2026). Ported 1:1 from the Bingo on giaovien.phongthiao.com
   (partner-web-demo BingoHelper/bingoHelper.module.css + Onboarding/BingoGuide/bingoGuide.module.css): porthole with the
   blue talking Rive Bingo, figure-8 hover with a star tail, fly-in once per session, gradient-ring bubble and panel.
   Landing-page differences: docks bottom-LEFT (Messenger / Zalo / phone / to-top own the bottom-right), and the panel
   lists the page's products instead of the app's screens. Every class starts with fb- (the page has its own CSS). */
