A real-time, multi-user spreadsheet (Google Sheets–style) built as a personal project: sign up, create workbooks with multiple sheets, invite collaborators, and edit concurrently.
Personal project for learning CRDT-based realtime systems, formula engines, grid virtualization, and disciplined AI-assisted development.
See CLAUDE.md for conventions and how we work, and PROJECT_CONTEXT.md for the rationale behind every major decision. The build plan lives in docs/PLAN.md.
