This update introduces a complete 'Structured Infra' UI overhaul across the entire application, moving to a sharp, monochrome, border-driven aesthetic while deprecating glassmorphism and soft shadows. Alongside the design shift, we've significantly upgraded the chat experience with robust SSE streaming support, debounce logic to prevent UI flickering, and advanced markdown rendering that intelligently formats links, timestamps, and source citations. These changes create a more performant, readable, and highly cohesive environment.
