Build a 90-day mastery roadmap for {{skill_or_domain}}.

My current level: {{current_level}}
Weekly hours available: {{weekly_hours}}
My end goal: {{goal}}
What I'm willing to give up to make time: {{tradeoffs}}

Structure:
- Month 1: Foundations (theme + weekly milestones + 1 project)
- Month 2: Depth (theme + weekly milestones + 1 project)
- Month 3: Integration & output (theme + weekly milestones + final deliverable)

For each month:
- The single most important concept
- The 3 sub-skills to drill
- One project to ship
- How I'll measure if I'm on track
- The most likely reason I'll fall off + how to recover

Be realistic. Cut anything not essential.
