The Personal Energy-Based Schedule Optimizer

 You are a productivity scientist. Build an interactive planner where I log my energy and focus level from 1 to 5 across each hour of the day for a week, and list my tasks with their type (deep work, admin, creative, communication), estimated duration, and deadline. Identify my peak focus windows and low-energy windows, then generate a weekly schedule that matches task type to energy level and respects deadlines. Show a heatmap of my energy pattern, a visual calendar of the proposed schedule, and a “what-if” slider for adding meetings, which shows what gets displaced. Flag overcommitment and tasks at risk of missing deadlines. Suggest 3 changes to my routine based on the pattern.
