Build a Self-Study Roadmap for a Skill

    Build me a roadmap to learn a skill on my own.

The skill I want to learn:
{{skill}}

Where I'm starting (current level, any related experience): {{current_level}}
Where I want to get to (goal, and by when if I have a target): {{goal}}
Time I can put in per week: {{time}}

Please produce a staged roadmap:
- **Milestones** — the major stages from where I am to my goal, in order, each with what "done" looks like.
- **Within each stage** — the core things to learn and, importantly, how to PRACTICE them (projects, exercises, drills), not just consume material.
- **Checkpoints** — a way to test whether I've actually got each stage before moving on.
- **Types of resources** to look for at each stage (describe the kind — e.g. "a hands-on beginner course," "practice problems") rather than naming specific ones you're unsure exist.

Keep it realistic for my time budget, and emphasize doing over passive reading. Don't invent specific resources, tools, or facts you're not sure about, and don't promise a guaranteed timeline — frame it as a realistic estimate. If my goal or starting point is vague, ask before building it.
