lcarli/academiaauditiva ? reverse-engineered prompt

Build me a web app for ear training called Academia Auditiva.

I want a clean ASP.NET Core site for musicians, music students, and audio engineers, with exercises for notes, intervals, chords, scales, rhythms, dictation, sight singing, and some audio training like level match, stereo position, and guess frequency. It should support piano, guitar, and violin playback, with a student choosing their instrument, and it should let teachers create classrooms, invite students by email, and assign routines like tests with due dates and reports.

Please include user accounts, roles for students, teachers, and admins, progress tracking, badges, streaks, daily challenges, free practice, and a dashboard that shows stats and weak spots. Make it available in English, Portuguese, and French, with light and dark themes. If possible, add guided onboarding, notifications, privacy features like data export and account deletion, and the usual health checks and deployment setup so it can run locally and in Azure. Use current docs online if you need to.
