alitavousi83/Google-Sheets-Time-Tracker ? reverse-engineered prompt

Build me a premium Google Sheets time tracker that turns a blank spreadsheet into a fully automated productivity dashboard.

I want it to create four weekly sheets and one monthly dashboard, with half hour time blocks for the whole week, dropdown activity choices, automatic color coding, and clear sections for daily to do lists, statistics, charts, and a reflection journal. It should also roll everything up into a monthly view with KPI cards, productivity score, weekly comparisons, activity trends, and monthly summaries.

Please make it feel polished and easy to use, with formulas and formatting set up automatically so I only have to change a time block and everything updates on its own. Include the main activity categories for sleep, programming, exercise, meditation, personal tasks, and wasted time. If you need to, look up current Google Apps Script docs online.
