<session_context>
This is a continuation of an ongoing session. Here's where things stand:

**User's Goal**: Build a Python web app

**Plan**:
  1. Create Flask project
  2. Add routes
  3. Add database
  4. Deploy

**Progress**:
  ✓ Created Flask project
  ✓ Added routes

<session_context_guidelines>
Use this context to maintain continuity:
- Reference earlier decisions and conclusions naturally
- Don't re-ask questions that have already been answered
- Build on established understanding rather than starting fresh
