just frontend-dev   # Terminal 3: Frontend dev server

# Option 1: Restart terminal and try again
just install

# Option 2: Install backend separately
just backend-install

# Option 3: Manual UV installation
irm https://astral.sh/uv/install.ps1 | iex
# Restart terminal, then: uv sync --all-extras

just db-start
just db-logs  # Check for errors
