- Nav: smaller padding, smaller text on mobile - Hero: clamp() font sizes scale from 1.75rem on mobile to 4.8rem on desktop - Hero: reduced padding (pt-12 on mobile vs pt-32 on desktop) - Tools grid: 1 column on mobile, 2 on sm, 4 on lg - Prism: 240px on mobile, 340px on desktop - Steps/CTA/Footer: responsive padding - CTA buttons: responsive sizing - All text uses clamp() for smooth scaling Closes iii123iii#3
- MergeService: streaming with MemoryUsageSetting (avoid OOM on large merges) - StorageService: SUM query instead of loading all documents (N+1 fix) - DocumentRepository: added sumSizeBytesByOwnerId query - AppSettingsRepository: @Cacheable on findById (eliminates repeated DB hits) - CacheConfig: @EnableCaching with ConcurrentMapCacheManager - application.yml: HikariCP pool tuning (20 connections, idle timeout) - application.yml: Hibernate batch fetching (batch_size=30, default_batch_fetch_size=16) - Performance tests: regression tests for all optimizations Closes iii123iii#2
