v1.1.2 — Infinite Scroll, Sidebar Filters & UI Overhaul

Added

• Infinite Scrolling: IntersectionObserver-based lazy loading replaces the static 100-icon limit. Backend API now supports start/limit pagination.
• Sidebar Filtering Engine: Dynamic sidebar fetches packs and styles from /api/filters on load.
• Premium Skeleton Loaders: Shimmering skeletons for both grid and sidebar, hardcoded into initial DOM to prevent layout shifts.
• Retina-Ready Favicon: Standalone favicon.svg with matching violet-to-cyan gradient.

Changed

• UI Architecture: Search bar is now centered in the header — native app-like layout.
• Typography: Migrated to Outfit Google Font with fonts-loaded pattern to eliminate FOIT.
• Layout Shift Fixes: Global custom scrollbar, scrollRestoration = manual, instant top-scroll on filter changes.
