Refresh promo banner kit — code-composited, on-brand, crisp

Regenerated hero 1200x630, 728x90, 468x60, 300x250, 160x600, 120x600 by
compositing the new logo + headline + mint CTA on a dark mint-glow ground
(canvas, not AI) so text is always crisp and on-brand. Leaderboard tagline
auto-fits; previews cache-busted (?v=2).
