I've converted the NeuroLife Mini HTML page into a polished Next.js application with a dark, dashboard-style design. The app is split into three clean components: EcoInputForm handles all user inputs (study hours, sleep, mood slider, screen time, transport, and food selects), EcoResults displays the analysis with productivity/eco score progress bars, burnout warnings, ecosystem health visualization using Lucide icons, AI insights, and future projections, and the page ties it all together with the same calculation logic from the original. The dark navy/cyan theme gives it a modern data-dashboard feel with proper semantic tokens throughout.
