FPGA-Core Tutorial

This tutorial tree follows ROADMAP.md. Each phase and subphase has a learning note with the same structure:

• Context
• Goals
• New Concepts
• How To Think About It
• Learning Tasks
• Pitfalls
• Tooling And Testing
• References

The notes assume strong Linux/systems experience and beginner-to-intermediate FPGA and digital-design experience. They intentionally avoid giving implementation code. The goal is to explain what to learn, what to verify, and what mistakes to avoid.
