How to follow this guide?

Each section is a standalone lesson page: read it fully without the video — diagram, example, step-by-step, FAQ and flashcheck included.
Sections of the current level appear in the sidebar on the left of each page.
Follow the levels in order (0 → 6) for steady progress, then validate with each level's hardened exam.
