/* ============================================================
   CINEPLUS — style.css
   Premium cinematic web app. Dark. Intentional. High-contrast.

   FIXES & ADDITIONS:
   - Carousel left-drift fixed: scroll-snap + left padding on track
   - Carousels are fully independent (each track scrolls separately)
   - Mobile: 2-column poster grid instead of broken stacked carousel
   - touch-action: pan-x on carousel tracks for mobile swipe
   - will-change: opacity on hero images (prevents repaint on crossfade)
   - All new sidebar styles (panel, overlay, profile, tabs, lists)
   - Skeleton loading animation for poster cards
   - poster-tap-hint overlay on hover/focus
   - All new classes from script.js: rating-chip, recommend-error-card,
     sr-only, no-scroll, nav-btn, google-btn, sidebar-*, carousel-error
   - Poster images: high-def quality via w500 TMDB (already set in JS)
   - Info layer: full-screen on mobile, scrollable content
   - Footer: updated styles with subtitle
