A slim footnote and a QR tile close the bottom. [Subject] No people. Two monumental translucent champagne-gold glass numerals glowing from within, standing on a red velvet-look podium with gold trim; scattered chocolate-gold coins, red gift boxes with gold ribbons and light streaks fill the air around the base. [Headline] Ribbon banner across the numerals in white caps on two lines: "BLACK FRIDAY MEGA SALE" and "NONSTOP PERKS". Gold bar: "Claim Big Coupons And Save More".

[Badges] Footer note: "All Black Friday perks stack; quantities are limited, first come first served" beside a small QR tile. [Mood] Grand, rewarding and jackpot-like; luminous gold-on-red gala abundance built around stacking coupons.
