The marquee scroll effect wasn't working because 'animate-marquee'
was defined as an inline CSS class, not a Tailwind utility. Tailwind's
JIT compiler strips unknown classes, so group-hover:animate-marquee
was being removed at build time.
Fix: Added 'marquee-scroll' keyframes and 'marquee' animation to
tailwind.config.js theme.extend. Now 'animate-marquee' is a proper
Tailwind utility that works with group-hover and responsive variants.
Also removed the inline <style> block from Player.tsx since the
animation is now handled by Tailwind.
App.tsx main element now has pb-24 (96px bottom padding) so the
gallery content always has breathing room above the fixed player bar.
Prevents content from sitting flush against the player controls.
