If you received this file on its own, the book is what explains it.

Standalone investment study website adapted from PRL Investment Lab INV-1.1.0. It includes stocks and cash, recurring contributions, and retirement withdrawals. No options modules, accounts, billing or API keys.

Upload this ZIP to a NEW Netlify project, or extract it and upload the folder containing index.html. Do not replace an existing PRL site with this smaller package. The browser runs the calculations. Open Method & help for assumptions and limitations.

Select SPY & Cash and run it. Save settings, change one input, and load the saved settings. Export a run and logbook for a durable record. Browser storage is local to that site and device; it can be cleared.

The calculation engine is unchanged from INV-1.1.0. It uses its own random-number method and calculation intervals. It does not reproduce Run 001 random paths simply by sharing its seed.

For revisions, give ChatGPT these files and describe one specific change. Request a complete replacement ZIP and checks of the affected features. Keep the previous working package.
