+/// OPTIMIZACIONES IMPLEMENTADAS:
+/// 1. Image caching con NSCache (BEFORE: Sin cache en memoria)
+/// 2. Preloading de páginas adyacentes (BEFORE: Carga bajo demanda)
+/// 3. Memory management para imágenes grandes (BEFORE: Sin control de memoria)
+/// 4. Optimización de TabView con lazy loading (BEFORE: Cargaba todas las vistas)
+/// 5. Thumbnail system para navegación rápida (BEFORE: Sin thumbnails)
+/// 6. Progress guardado eficientemente (BEFORE: Guardaba siempre)
+/// 7. View recycling para páginas (BEFORE: Nueva vista por página)
