flvani/diatonic-map — reverse-engineered prompt

I want a simple browser app for learning diatonic accordion. The main thing is an interactive button map where someone can pick an accordion layout and click buttons to see the note names and hear the sound for push and pull. It should also help with common chords, basic tablature, and practice material, so a learner can explore songs and fingerings instead of just looking at a static chart.

Please make it feel like a small teaching tool, not just a demo. It should have clear screens for the accordion map, songs or repertoire, chords, and practice, with audio that works in the browser. If the project already hints at multiple languages, keep that idea so the interface can be translated. A clean layout for desktop and mobile would be great.

Use what is already in the repo and wire it up into something usable end to end. If you need details about accordion notation or browser audio, look up current docs online.
