VicenteBarrientos/condosync-community ? reverse-engineered prompt

Build me a web app for managing condo common expenses in Chile.

I want an admin side where someone can create monthly fees, split costs by coefficient, add reserve fund and late interest, track payments, and generate each resident’s statement. It should also have a resident portal so people can log in and see what they owe, their history, and downloadable PDF slips or statements. Include notices by email, a simple way to prepare WhatsApp messages, and support for bank reconciliation and importing spreadsheets with clear validation.

Use the existing database and auth setup, keep all money in CLP as integers, and make sure each condo and unit stays isolated from the others. It’s fine if some integrations like payments, AI import help, or email are optional and can be turned off in demo mode. The demo should use synthetic data only and never send real external requests.

If you need to check current docs for any integration details, go ahead and look them up online.
