Cambios implementados: 1. Lazy loading de imágenes: - catalog.js: loading="lazy" decoding="async" en part cards y detail panel - inventory.js: lazy loading en imagen de detalle de item 2. Minificación de assets: - scripts/minify-assets.sh: minifica JS (terser) y CSS para POS y Dashboard - 25 archivos .min.js + 5 .min.css generados en pos/static/ - 14 archivos .min.js + 8 .min.css generados en dashboard/ 3. Nginx auto-serve minified: - try_files $1.min.js antes de servir .js original - try_files $1.min.css antes de servir .css original - Transparente para los templates HTML (cero cambios en HTML) 4. Cache warming script: - scripts/warm_vehicle_cache.py: pobla Redis con vehicle info por batches - Mitiga DISTINCT ON + 4 JOINs sobre 2B filas - Corre en background, procesa ~1.5M parts Tests: 73/73 pasando
