feat(site): smoother motion across the landing pages

- Slow Ken Burns drift on the hero artwork for cinematic depth.
- Gentle breathing pulse on the brand glows behind Frank and the hero.
- Silkier reveal easing (cubic-bezier .22/1/.36/1, 0.55s) site-wide.
- Eased, longer hover transitions on the hero CTAs.
- Smooth page scrolling, all guarded by prefers-reduced-motion.
