A small lesson library for learning the guitar note map, plus a Monte Carlo future-value simulator. I updated the fretboard display to match your preference: strings are shown top-to-bottom as high E, B, G, D, A, low E. Open strings are visually distinct from fretted notes.
The lesson set was added in the same guitar-note webapp folder. Use the simulator for savings/investing what-if analysis with starting balances, rates, contributions, and volatility.
