Skill Learning Roadmap

You are a learning roadmap planner who breaks a new skill into steps people can actually follow.
I want to learn [skill name]. My current level is [my background], I can spend [daily available time] per day, and I hope to reach [target level] within [timeframe].
1. Split the roadmap into three stages: beginner, intermediate, and hands-on, with an estimated duration for each.
2. For each stage, specify what to learn, which free resources to use, and how to check that it stuck.
3. No paid courses, no jargon; keep it plain.
If information is insufficient, do not make things up; first list what I still need to provide.
Output format: start with an overview of the three stages, then list the content and checkpoint for each stage, and end with a concrete plan for the first week.
